Authorities are investigating a spate of bomb threats that began earlier this week and reached a new level of urgency on Wednesday, when prominent Democrats like former President Obama, Hillary ClintonHillary Diane Rodham ClintonThe Memo: Trump faces steep climb to reelection What the Mueller report tells us about Putin, Russia and Trump's election Steve Bullock puts Citizens United decision at center of presidential push MORE and others, as well as CNN, were targeted in what appears to be a coordinated effort.

Investigators have not yet identified any suspects or motives, and no deaths or injuries have been reported. The FBI said on Wednesday it is continuing to investigate the packages and warned the public there may be more that have not been found.

Below is a timeline of the events that have raised new fears about the level of violence in a country already polarized.

Monday evening: Explosive device discovered at George Soros’s house

An employee working for Democratic philanthropist George Soros finds an explosive device in a mailbox at Soros's residence in Westchester County, N.Y.

Authorities are alerted and a bomb squad detonates the device. Soros, a frequent political target of the right both in the U.S. and Europe, was not home when the explosive device was discovered.

Tuesday night: Secret Service finds explosive in mail sent to Clintons

The Clintons were not “at risk of receiving (the package),” according to the Secret Service.

Hillary Clinton, who as Donald Trump's former opponent in the 2016 presidential election has become been one of the right’s most common foils, has faced unfounded rumors such as the “Pizzagate” conspiracy. Crowds frequently chant “lock her up” at rallies.

Early Wednesday morning: Authorities intercept explosive sent to Obama

The Secret Service says it intercepted a package early Wednesday morning that was addressed to former President Obama’s home in Washington, D.C.

The package was identified during routine screening procedures as a potential explosive device, the Secret Service says in a statement, adding that the device was “appropriately handled as such.” The agency also says that Obama and the Clintons "did not receive the packages nor were they at risk of receiving them.”

Wednesday, 10:10 a.m.: CNN evacuated after suspicious package found

Employees in the Time Warner building in New York, which houses CNN’s offices, are forced to evacuate after an alarm sounds. CNN anchors Poppy Harlow and Jim Sciutto are forced to abandon their broadcast mid-air, and they later resume the broadcast from the street.

The evacuation is caused by a suspicious package in the mailroom addressed to former CIA Director John BrennanJohn Owen BrennanThe Hill's Morning Report - White House, Congress: Urgency of now around budget Dems ask former CIA chief John Brennan for Iran briefing: report Brennan hits Trump for calling Mueller probe a 'coup': These are 'sociopathic ramblings' MORE, a frequent critic of Trump, who does not work for CNN but serves as an NBC/MSNBC senior national intelligence analyst. Trump notably revoked Brennan’s security clearance in August, in an unprecedented move critics slammed as an attempt to silence dissent.

CNN has also frequently drawn Trump’s ire, with the president ripping the cable network, as well as other outlets, as “fake news.”

Wednesday, around 11 a.m.: White House, GOP condemn attempted attacks

The White House and prominent Republican leaders on Wednesday morning condemn the attempted attacks against Obama, the Clintons and CNN.

Vice President Pence writes on Twitter that the “cowardly actions are despicable & have no place in this Country.”

White House press secretary Sarah Huckabee Sanders in a statement condemns the attempted attacks, calling them “despicable” and saying that “anyone responsible will be held accountable to the fullest extent of the law.” In a tweet later during the day, Sanders clarifies that her condemnation “certainly includes threats made to CNN.”

Trump breaks his silence on the events early Wednesday afternoon, saying “I agree wholeheartedly” in a message that retweets Vice President Pence. Pence wrote: “We condemn the attempted attacks against fmr Pres Obama, the Clintons, @CNN & others. These cowardly actions are despicable & have no place in this Country. Grateful for swift response of @SecretService, @FBI & local law enforcement. Those responsible will be brought to justice.”

Hillary Clinton on Wednesday responds to the explosive devices being sent to her and others, calling the incidents a sign of “deep divisions” in the United States.

Wednesday, 12:45 p.m.: New York officials hold press conference 

New York Governor Andrew Cuomo, New York City Mayor Bill de Blasio and New York Police Department commissioner James P. O'Neill hold a press conference to address the packages.

All three encourage New Yorkers to go about their daily lives and say the city and its residents would not be perturbed by the packages.

“Terrorism only works if you let it work. What they are trying to do is scare us and destabilize us and we will not let that happen…We will not let these terrorist thugs to change the way we live our lives. They fail unless we allow them to win, and we will not allow them to win,” Cuomo says.

“This clearly is an act of terror attempting to undermine our free press and leaders of this country through acts of violence. I want to make very clear that the people of New York City will not be intimidated…We cannot be terrorized if you refuse to allow the terrorists to win,” de Blasio echoes.

Cuomo reveals during the press conference that his Manhattan office has received a package containing an explosive device. Police later confirm that the package contained a thumb drive, not an explosive device, and it was unrelated to other packages containing the explosive devices.

Reports emerge that police have intercepted a suspicious package sent to Rep. Maxine Waters (D-Calif.).

Waters confirms the suspicious package in a statement Wednesday. She also thanks law enforcement and condemns "any and all acts of violence and terror."

"We are extremely angry, upset, unhappy about what we witnessed this morning and we will get to the bottom of it," he added.

Wednesday late afternoon: FBI confirms it's still investigating

The FBI releases a statement detailing the information known so far and confirming that it has sent the packages to Quantico for analysis. 

The bureau appears to be going by the assumption that the various bomb threats are linked. It identifies the known targets of the packages so far as Soros, Clinton, Obama, Brennan and Holder, but acknowledges that there still might be more packages that haven't been found.

“We have committed the full strength of the FBI’s resources and, together with our partners on our Joint Terrorism Task Forces, we will continue to work to identify and arrest whoever is responsible for sending these packages,” FBI Director Christopher Wray says in a statement.
