President Obama on Friday rejected Donald TrumpDonald TrumpRealClearPolitics reporter says Freedom Caucus shows how much GOP changed under Trump Jake Ellzey defeats Trump-backed candidate in Texas House runoff DOJ declines to back Mo Brooks's defense against Swalwell's Capitol riot lawsuit MORE’s case that violence, crime and immigration are threatening the country’s very foundation less than a day after the businessman officially claimed the Republican presidential nomination. 
“This idea that America is somehow on the verge of collapse, this vision of violence and chaos everywhere does’t really jibe with the experience of most people,” Obama said during a joint news conference with Mexican President Enrique Peña-Nieto at the White House. 
In November’s election, Obama said it’s natural that there will be “different visions of where we go as a country.”
“But we’re not going to make good decisions based on fears that don’t have basis in fact,” he added. 
It was the president’s first response to Trump’s Thursday night speech at the Republican National Convention, in which the party’s standard bearer painted a bleak picture of the United States and positioned himself as a singular figure who could fix the nation’s problems. 
Obama appeared dismissive of Trumps’s speech, saying that he didn’t take the time to watch the GOP convention live on television and only read about it later. “I don’t think that’s a surprise, I got a lot of stuff to do,” he said. 
But then the president rattled off a litany of statistics showing that rates of murder, violent crime, intentional killings of police officers and illegal immigration are lower than they were before he took office, seeking to undercut the central arguments of Trump’s speech. 
"America is much less violent than it was 20, 30 years ago, and immigration is much less a problem than it was not just 20, 30 years ago, but when I came in as president,” he said. 
"All the good things that are happening in America don't get reported on a lot."
During his speech in Cleveland, Trump argued that free trade deals have hollowed out the middle class and led to inner city violence and poverty. 
He cited murders carried out by undocumented immigrants, shootings of police in Dallas and Baton Rouge, La., and terror attacks in Orlando and San Bernardino, Calif., as evidence the country is spiraling out of control. 
“We’re not going to have our country anymore" without drastic changes, he argued.
Just the image of Obama standing beside his Mexican counterpart was meant to undercut Trump’s arguments on trade and immigration.

But he spoke about the “unbreakable” bond between the U.S. and Mexico, noting that many citizens of both nations live and work on both sides of the border — remarks that stood in contrast with Trump’s call to build a giant wall on the southern border. 
Peña-Nieto showered praise on the North American Free Trade Agreement, which Trump has pledged to renegotiate. 
Obama also listed the benefits of the trade ties between both countries. Looking to rebut Trump’s protectionist message, Obama said that the era of globalization is here to stay.
“We’re not going to be able to build a wall around that,” he said.
