The top Trump tweets of 2017

President TrumpDonald John TrumpTrump calls for Republicans to be 'united' on abortion Tlaib calls on Amash to join impeachment resolution Facebook temporarily suspended conservative commentator Candace Owens MORE frequently kept the political world off-balance with his Twitter account over the course of his first year in office, sending hundreds of tweets.

Trump has said he finds Twitter a useful tool to circumvent the press and speak directly to his nearly 45 million followers.

But the president has also used Twitter to undermine his Cabinet, to attack lawmakers in his own party, to set in motion policies that have caught government officials by surprise and to scold U.S. allies abroad.

Here are 20 memorable tweets from a busy year in Trump’s Twitter timeline, presented in no particular order:

1) Obama wiretap 

Trump’s claim — presented without evidence — that former President Obama spied on him at Trump Tower was met with outrage and incredulity by the press and the president’s critics. 

In a later tweet, Trump claimed that Obama “was tapping my phones in October, just prior to Election” and called his predecessor a “bad (or sick) guy.”

Senior administration officials were forced to defend the claim on a daily basis at briefings and on cable news interviews. 

But the White House never backed down, even after former FBI Director James ComeyJames Brien ComeyGiuliani strikes back at Comey: 'No one really respects him' Comey: Barr is 'sliming his own department' Trump says campaign was 'conclusively spied on,' calls it 'treason' MORE testified under oath before Congress that there was no truth to the claim. 

Trump later claimed vindication after media reports that Trump’s former campaign chairman Paul ManafortPaul John ManafortUkrainian who meddled against Trump in 2016 is now under Russia-corruption cloud Feds ask judge to postpone ex-Trump campaign aide's sentencing Giuliani cancels trip to Ukraine to press Biden investigation MORE had been wire-tapped and that the FBI had obtained a FISA warrant related to a Russia probe to spy on Trump officials during the transition.

But Trump’s claim that Obama had wire-tapped Trump Tower would give his detractors and the media ammunition to question the White House’s truthfulness, an issue that would soon become a running problem for the administration. 

2) Puerto Rico  

Trump attacked the mayor of San Juan and criticized Puerto Rico’s infrastructure, debt and dependence on the federal government while the island territory was in the midst of a humanitarian crisis brought on by Hurricane Maria.

Critics had already accused the administration of being slow to react to the disaster in Puerto Rico, contrasting the government’s response there to the widely praised rescue and relief efforts that were underway in the wake of hurricanes and floods that had ravaged the Gulf Coast.

Democrats condemned Trump’s tweeted attacks against Puerto Rican officials, as well as his claim that Puerto Ricans were not doing enough to help themselves as racist and heartless.

3) Michael Flynn 

While fundraising for Republicans in New York City, someone with access to Trump’s account tweeted that Trump had fired his former national security adviser Michael Flynn for lying to Vice President Pence and the FBI about the extent of his contacts with Russians. 

Trump had previously said he fired Flynn only for lying to Pence. Trump’s claim that he knew Flynn had lied to the FBI seemed certain to attract the attention of Robert Mueller’s special counsel, which had just secured a guilty plea from Flynn.

If Trump had fired Flynn for lying to the FBI and then asked Comey to drop the investigation, as Comey has claimed, it could give credence to the idea that the president had sought to obstruct justice in the case.

Trump’s lawyer, John Dowd, later claimed he was responsible for the tweet. Dowd apologized and called it a mistake. 

4) 'Radical Islamic Terrorism' 

On Nov. 29, Trump retweeted a series of unconfirmed videos purporting to show violent acts by Muslims, which were first sent out by Jayda Fransen, a leader of a far-right nationalist party in Great Britain. The tweets are no longer available online because Fransen’s account has been suspended under Twitter’s new rules governing hate speech on the social media platform.

The anti-Muslim videos set off a firestorm: Democrats renewed calls for Trump to be impeached and British Prime Minister Theresa May condemned the tweets as “prejudiced rhetoric of the far right” and said “it is wrong for the president to have done this.”

The White House defended the tweets, saying they drew attention to the problem of radical Islamists and highlight the president’s agenda on national security. 

But Trump’s response to May — telling her to worry about her own country — further complicated relations between the U.S. and a key ally.

And it raised questions about where Trump gets his news and whether he buys into conspiracy theories.

On the same day, Trump used Twitter to resurface unfounded allegations that MSNBC host Joe Scarborough, a fierce critic of the president, was somehow involved in the death of one of his former interns.

5) James Comey "tapes" 

A week after firing Comey, the president suggested over Twitter that he had secretly recorded their private conversations.

The veiled threat has haunted Trump ever since. Comey said the tweet prompted him to leak the personal memos he wrote detailing his encounters with Trump — including his claims that the president had asked him for loyalty and leniency for Flynn.

Trump later said he was bluffing about the recordings to keep Comey honest in his testimony about their encounters. 

6) Trump versus the NFL

Trump dove headlong into the culture wars in October with a series of tweets expressing his disgust with NFL players for kneeling during the national anthem to protest racial inequality and police brutality.

The president would continue the attacks throughout the season, calling on individual players to be cut or suspended, attacking an ESPN anchor who called him racist, mocking NFL commissioner Roger Goodell for his handling of the protests and gloating over the league’s ratings struggles.

Vice President Pence would later walk out during an Indianapolis Colts game. 

While the White House seemed to successfully turn the debate into one about American pride and support for the troops, polls show the public disapproved of both the president’s attacks and the players’ decision to kneel during the anthem.

7) North Korea diplomacy 

Trump’s Twitter diplomacy has caused panic in the foreign policy establishment, where there are grave concerns that the president’s tweets will escalate a confrontation between the U.S. and North Korea.

Over Twitter, Trump has relished calling North Korean leader Kim Jong Un “rocket man,” while also mocking him for being “short and fat.” 

Trump has also undermined Secretary of State Rex TillersonRex Wayne TillersonOvernight Defense: Trump rails against media coverage | Calls reporting on Iran tensions 'highly inaccurate' | GOP senator blocking Trump pick for Turkey ambassador | Defense bill markup next week Trump frustrated with advisers over Iran, wants to speak to leaders in Tehran: report Juan Williams: Trump's scorecard is rife with losses MORE over Twitter, saying he is “wasting his time trying to negotiate with Little Rocket Man” and that the U.S. will “do what has to be done.” 

Tillerson has been working on a diplomatic solution to the North Korean nuclear program, an effort that has been complicated by Trump’s public Twitter pronouncements. 

8) Jeff SessionsJefferson (Jeff) Beauregard SessionsMSNBC host: Barr 'the most dangerous person' who works for Trump Chris Wallace: AG Barr 'clearly is protecting' Trump Appeals court rules Trump end of DACA was unlawful MORE  

Trump’s attack against Attorney General Jeff Sessions was a shocking lesson in how the president could turn on one of his most loyal allies.

The president appointed Sessions to lead the Justice Department knowing he who would crackdown on illegal immigration and drugs, fulfilling key promises Trump made during the campaign.

But Trump was furious that Sessions recused himself from matters pertaining to Russia, paving the way for the special counsel investigation that has cast a cloud over Trump’s first year in office.

Trump’s attacks against Sessions have continued throughout the year. Rather than taking the drastic step of firing Sessions, Trump seems content to make his life miserable. Many of the president’s allies have since taken up the torch and are demanding Sessions shut down the special counsel probe or step aside to make room for someone who will.

9) Transgender military debate 

Trump took the Pentagon by surprise when, seemingly out of nowhere, he announced over Twitter that he would ban transgender people from serving in the military.

The tweet caused chaos and confusion and was condemned by critics in both parties as bigoted and unnecessarily cruel to some active service members.

A month later, Trump followed up on the tweet in a memo that instructed the Defense Department to stop accepting transgender recruits.

That directive is tied up in the courts, with a federal judge recently ruling that the Trump administration must accept transgender recruits into the military by Jan. 1. Last week, a federal appeals court ruled against the administration’s efforts to delay that ruling. 

10) Charlottesville, Va.

In a series of weekend tweets, Trump addressed the racially charged violence that broke out at a white supremacist rally in Charlottesville, Va. The tweets expressed vague sentiments of unity, but did not specifically call out the white supremacists at the center of the deadly violence.

Trump would later be pilloried for saying there was blame to go around “on many sides,” an equivocal response to the racially charged violence that is widely viewed as a low point of his presidency.

The president later sought to walk back his remarks, specifically condemning racism and disavowing racist groups while complaining over Twitter that the “truly bad people” in the media had not paid attention to his “additional remarks.”

But the damage had been done. Less than a week later, Trump revisited the controversy by lamenting over Twitter that he was “sad to see the history and culture of our great country being ripped apart with the removal of our beautiful statues and monuments.”

11) Sexual harassment  

Trump injected himself into the national debate over sexual harassment in November, tweeting an attack against Sen. Al FrankenAlan (Al) Stuart FrankenHirono electrifies left as Trump antagonist Miss USA pageant winner celebrated for addressing 'Me Too' movement on stage NY man sentenced to prison for racist death threats to Obama, Waters MORE (D-Minn.), who has been accused of groping and forcibly kissing several women.

By doing so, the president opened himself up to charges of hypocrisy. More than a dozen women have accused the president of inappropriate touching or unwanted sexual advances. 

And Trump’s critics accused him of holding a double-standard by condemning Democrats accused of sexual harassment, even as he backed Republican Senate candidate Roy MooreRoy Stewart MooreRoy Moore wants judge who ruled against him removed from case The Hill's Morning Report - Lawmakers split over Mueller findings: 'case closed' vs. 'cover-up' Roy Moore 'seriously considering' another Senate bid MORE in Alabama, who had been accused of molesting teenage girls.

In his resignation speech, Franken noted the “irony" in the fact that he was resigning from the Senate while a man who "bragged" about his history of sexual assault is still in the White House. 

In a later tweet, Trump would pile on disgraced “Today” host Matt LauerMatthew (Matt) Todd LauerRobin Roberts, Gayle King most trusted morning show hosts: poll Press: In defense of Joe Biden Fewer men say sexual harassment in the workplace is major problem: Gallup MORE, who was fired amid a slew of sexual harassment allegations against him.  

12) Robert Mueller  

The White House has tried to avoid conflict with special counsel Mueller and his team, preferring instead to cooperate with the investigation in the hope that the president will be cleared and the shadow over his presidency removed as soon as possible. 

But that hasn’t stopped Trump from occasionally questioning the motives of Mueller’s investigators and lashing out over Twitter at what he calls a partisan “witch hunt.” 

Trump would return to the “witch hunt” claim on Oct. 29 in a series of tweets claiming that there was a Democratic conspiracy against him and complaining that Hillary Clinton had gotten a free pass from investigators.

The next day, Trump’s former campaign chairman Paul Manafort was indicted on a litany of financial charges.

13) Mika Brezinski 

Trump despises his cable news critics on MSNBC’s Morning Joe, anchored by Joe Scarborough and his fiancée, Mika Brzezinski. 

But Trump’s attack on Brzezinski for getting cosmetic surgery was surprising for its ferocity, even by Trump’s standards. 

The tweet was condemned by many as sexist, with critics pointing to Trump’s past Twitter attacks against women. The president had previously called anchor Megyn Kelly a “bimbo” on Twitter. 

14) Mitch McConnellAddison (Mitch) Mitchell McConnellOn The Money: Treasury rejects Dem subpoena for Trump tax returns | Companies warn trade war about to hit consumers | Congress, White House to launch budget talks next week | Trump gets deal to lift steel tariffs on Mexico, Canada Schumer calls on McConnell to hold vote on Equality Act House Dem cites transgender grandson in voting for Equality Act MORE and ObamaCare  

Trump’s attack against Senate Majority Leader Mitch McConnell (R-Ky.) after the Senate failed to pass a bill to repeal ObamaCare forced Republicans to take sides at a time when the party’s agenda appeared hopelessly stalled on Capitol Hill.

Washington Republicans rallied around McConnell and were frustrated by Trump’s insistence on attacking the person he needs to move his agenda through the Senate. Gleeful grass-roots conservatives demanded McConnell step aside and vowed war against the majority leader and his allies.

The feuding raised questions about whether the GOP would spoil its majorities in Congress over intraparty infighting. But Trump and McConnell finished the year praising one another on the South Lawn of the White House after a victory on tax reform.

15) Kirsten GillibrandKirsten Elizabeth GillibrandOvernight Health Care — Presented by Campaign for Accountability — Momentum builds for federal laws enshrining abortion rights | Missouri lawmakers approve bill banning abortions at 8 weeks | Warren unveils plan to protect abortion rights 2020 Dem Seth Moulton calls for expanding cannabis access for veterans Momentum builds behind push to pass laws enshrining abortion rights MORE

Trump lashed out at Sen. Kirsten Gillibrand (D-N.Y.), a potential 2020 presidential candidate, after the New York Democrat said the president should resign over the allegations of sexual harassment against him.

For a potential Democratic presidential candidate, there is no greater windfall than to be the subject of a tweeted Trump attack. Facing Trump’s social media wrath can boost a politician’s national profile, energize the grass roots and incite a wave of donations. 

Sen. Elizabeth WarrenElizabeth Ann WarrenHere are the potential candidates still eyeing 2020 bids Sanders unveils education plan that would ban for-profit charter schools Warren policy ideas show signs of paying off MORE (D-Mass.), who Trump disparages as “Pocahontas” over Twitter, has seen her own profile rise after Trump attacks.

16) #FakeNews 

Trump elicited outrage from the press for tweeting out a video showing him body-slamming a man with the CNN logo emblazoned on his head at a fake wrestling match.

Many in the media described the video as a direct threat with the potential to incite violence against reporters. There was a race to determine who had created the video, and CNN came under fire for tracking the person down and only keeping him anonymous on the condition that he never engage in “ugly behavior” on social media again.    

Trump’s attacks on the press have been a hallmark of his first year in office. Recently, he went on Twitter to say a “fake news trophy” should be given out to the most dishonest outlet.

The press has accused Trump of using the “fake news” moniker for stories he doesn’t like, while the president’s critics have warned about the dangers of casting doubt on the free press.

But Trump’s offer of a fake news trophy foreshadowed the rockiest week for the media of the year.

Days later, ABC News suspended one of its top political reporters for getting a Russia-related story wrong, and CNN retracted a story claiming that Donald Trump Jr.Donald (Don) John TrumpUkraine's top prosecutor says no evidence of wrongdoing by Bidens New financial disclosure forms provide glimpses of Trump's wealth Trump's Doral resort revenue has dropped since presidential campaign: report MORE had been given special access to hacked Democratic emails by WikiLeaks before they were released to the public, giving the president and his allies fresh political ammunition in the fight. 

17) "Covfefe"

The infamous “covfefe” tweet spawned countless memes, late-night comedy jokes and T-shirts, showing the grip Trump’s Twitter account has on pop culture.

Trump’s critics had a field day with the misfired tweet, sent at 12:06 a.m. and deleted about six hours later.

Trump also showed a sense of humor about it, tweeting later in the day: “Who can figure out the true meaning of “covfefe” ??? Enjoy!”

18) Foreign policy

Trump was less than a week into his presidency when one of his tweets provoked a foreign leader to cancel a planned meeting.

Mexican President Enrique Peña Nieto dashed a planned meeting between the two after Trump reiterated his claim that Mexico would pay for a wall along the southern border.

It is part of a pattern of Trump alienating longtime U.S. allies and partners over Twitter.

In June, Trump attacked London Mayor Sadiq Khan in the wake of a terror attack in the British capital after Khan said there is "no reason to be alarmed.” The president also feuded over Twitter with British prime minister Theresa May, who was offended when Trump tweeted out videos purporting to show Muslims committing acts of violence. 

19) LaVar Ball 

It was a pop culture showdown between Trump and LaVar Ball, the father of basketball sensations who has made a career of unapologetic self-promotion that many view as “Trump-ian” for its bombast.

Trump felt slighted that Ball refused to give him credit for springing his son, a UCLA basketball player, from a Chinese prison after he was arrested on shoplifting charges. But like Trump, Ball does not like being told what to do.

The White House insisted that Trump was “happy to intervene,” but the tweet showed there is no one Trump won’t tangle with if he believes he is not getting due credit.

20) "Chuck and Nancy"

Senate Minority Leader Charles SchumerCharles (Chuck) Ellis SchumerGetting serious about infrastructure Schumer calls on McConnell to hold vote on Equality Act 'SleepyCreepy Joe' and 'Crazy Bernie': Trump seeks to define 2020 Dems with insults MORE (D-N.Y.) and House Democratic Leader Nancy PelosiNancy Patricia D'Alesandro PelosiTlaib calls on Amash to join impeachment resolution 5 things to watch as Trump, Dems clash over investigations GOP lawmaker: Trump has engaged in multiple actions that 'meet the threshold for impeachment' MORE (Calif.) abruptly pulled out of a meeting with Trump to negotiate federal spending after the president attacked them over Twitter, greatly enhancing the possibility of a government shutdown.

It was evidence of Trump’s tweets having a real-world impact. Liberals cheered the Democratic leaders for fighting back rather than absorbing Trump’s blows.
