Disability advocates and members of both political parties are calling out former President Donald Trump after he described Vice President Kamala Harris as “mentally impaired” and “mentally disabled.”

Trump made the comments at a rally in Wisconsin on Saturday and reiterated the personal attacks while campaigning in Pennsylvania on Sunday.

“Joe Biden became mentally impaired,” the former president said. “Kamala was born that way.”

“If you think about it, only a mentally disabled person could have allowed this to happen to our country,” Trump continued, in an effort to tie Harris to the current administration’s border policies.

Maria Town, president and CEO of the nonpartisan American Association of People with Disabilities, blasted Trump’s rhetoric for perpetuating stereotypes and being dismissive of the millions of voters with disabilities.

“Trump holds the ableist, false belief that if a person has a disability, they are less human and less worthy of dignity. These perceptions are incorrect, and are harmful to people with disabilities,” Town said, noting that many former presidents dating back to George Washington have had disabilities.

“To be clear, the insult of Donald Trump’s comment is not the suggestion that Vice President Harris is disabled, but rather, the insinuation that having a disability is synonymous with poor performance as a prospective president,” she said.

Fellow Republicans quickly sought to distance themselves from Trump’s remarks.

“I think that’s insulting not only to the vice president, but to people who actually do have mental disabilities,” Larry Hogan, a former Republican governor of Maryland who is running for Senate, told CBS.

Sen. Lindsey Graham, R-S.C., said during an appearance on CNN that Trump should take a different approach.

“I just think the better course to take is to prosecute the case that her policies are destroying the country,” Graham said.

Meanwhile, Illinois Gov. JB Pritzker, a Democrat, said that Trump turns to name calling because he doesn’t have anything good to offer everyday people.

“I think whenever he says things like that he’s talking about himself but trying to project it onto others,” Pritzker said.
