WASHINGTON — Republicans on Sunday sought to distance themselves from Donald Trump’s latest insults of Democratic nominee Kamala Harris during a rambling weekend rally in Wisconsin in which he called her “mentally disabled.”

Trump escalated his personal attacks on the vice president during what was billed as a speech on immigration following Harris’ trip to the U.S.-Mexico border.

“Joe Biden became mentally impaired,” Trump said. “Kamala was born that way. She was born that way. And if you think about it, only a mentally disabled person could have allowed this to happen to our country. Anybody would know this.”

Trump has already falsely claimed Harris “turned Black” and regularly insults her as “stupid,” “weak,” “dumb as a rock” and “lazy.” With just over a month left before the presidential election, his allies pushed him publicly and privately to talk instead about the economy, immigration and other issues.

“I just think the better course to take is to prosecute the case that her policies are destroying the country,” said Sen. Lindsey Graham, R-S.C., on CNN’s “State of the Union” when asked about Trump’s comments. “They’re crazy liberal.”

When asked whether he approved of the remarks, Rep. Tom Emmer, R-Minn., sidestepped during an interview on ABC’s “This Week.”

“I think Kamala Harris is the wrong choice for America,” said Emmer, who is helping Trump’s running mate JD Vance prepare for Tuesday’s vice-presidential debate. “I think Kamala Harris is actually as bad or worse as the administration that we’ve witnessed for the last four years.”

When pressed, Emmer said: “I think we should stick to the issues. The issues are, Donald Trump fixed it once. They broke it. He’s going to fix it again. Those are the issues.”

Harris would be the first woman, Black woman and person of South Asian descent to be president, has not commented on Trump’s recent attacks. She has said when asked about other comments, that it was the “same old show. The same tired playbook we’ve heard for years with no plan on on how he would address the needs of the American people.”

Trump said last month that he was “entitled” to personal attacks against Harris.

“As far as the personal attacks, I’m very angry at her because of what she’s done to the country,” he told a news conference then. “I’m very angry at her that she would weaponize the justice system against me and other people, very angry at her. I think I’m entitled to personal attacks.”
