2020 candidate Beto O'Rourke told CNN's Jake Tapper on Sunday that President Trump's "bizarre behavior," including his retweet of an unsubstantiated conspiracy theory about Jeffrey Epstein's death, is a distraction for the American people who want to see real solutions on gun violence and white nationalism.

TAPPER: "I do want to get your reaction to the president retweeting this unhinged conspiracy theory, without any evidence, linking [Jeffrey] Epstein's death by apparent suicide to a murder by the Clintons. What was your reaction when you saw the tweets?"

O'ROURKE: "This is another example of our president using this position of public trust to attack his political enemies with unfounded conspiracy theories. And also to try to force you and me and all of us to focus on his bizarre behavior instead of the fact that we just lost 22 people in this community, 9 people in Dayton, Ohio. We're seeing an epidemic of gun violence every single day in this country. ... He's changing the conversation, and if we allow him to do that, then we will never be able to focus on the true problems, of which he is a part."

Dozens of Democrats have called on the administration to take real action against gun violence by reconvening the Senate to vote on 2 House-passed background check bills. O'Rourke, who suspended his campaign after the shooting in his hometown, has said he would consider mandatory gun buyback programs or gun licenses if elected president.

O'Rourke also called attention to a CNN report this week that claimed the White house has rebuffed efforts by the Department of Homeland Security to make "combating domestic terror threats, such as those from white supremacists, a greater priority."

"[Trump] has ignored them, or willfully suppressed action on those ideas and those programs and those policies that could have saved lives in El Paso and across the country," O'Rourke said.
