President Donald Trump appears to think the best response to the problem of gun violence in the U.S. is to focus on mental illness ― specifically, to build more mental institutions.

Before Trump’s reelection campaign rally in New Hampshire on Thursday, the president was asked by a reporter about what kind of executive actions he was prepared to take on gun violence.

“We’re looking at the whole gun situation. I do want people to remember the words ‘mental illness.’ These people are mentally ill. And nobody talks about that,” Trump responded.

“I think we have to start building institutions again,” he added, saying that mental institutions were closed in the 1960s and 1970s and “the people were just allowed to just go onto the streets ― that was a terrible thing for our country.”

“We have to open up institutions ― we can’t let these people be on the streets,” he added.

Earlier this month, there were two mass shootings in one weekend in the U.S: in El Paso, Texas, where a gunman killed 22 people, and in Dayton, Ohio, where a shooter killed nine people.

The suspected shooter in the El Paso massacre is believed to have posted a racist, anti-immigrant manifesto about his motivations, railing against a “Hispanic invasion” of Texas in an echo of the president’s racist rhetoric.

Research shows that most mass killers don’t have severe mental health problems. Experts have also long repeated that most people with mental health issues are not violent but are actually more likely to be victims of violence.

HuffPost reached out to the White House to clarify but did not immediately receive a response.
