Acting White House chief of staff Mick Mulvaney faced pushback from “Fox News Sunday” host Chris Wallace after he claimed President Donald Trump’s attacks on lawmakers of color have nothing to do with race.

Trump has faced intense backlash since he bashed Rep. Elijah Cummings (D-Md.), who is black, and his majority-black congressional district that includes much of Baltimore on Saturday.

Cummings’ district “is a disgusting, rat and rodent infested mess,” the president tweeted in response to the Maryland lawmaker criticizing inhumane conditions at migrant detention centers along the southern border of the U.S. “No human being would want to live there.”

Trump’s anti-Baltimore Twitter rant came less than two weeks after he wrote that a group of Democratic congresswomen of color known as “the Squad” should “go back” to other countries.

“Nobody objects to the president defending his border policies but this seems, Mick, to be the worst type of racial stereotyping,” Wallace told Mulvaney during their exchange on “Fox News Sunday.” “Is he saying people who live in Baltimore are not human beings?”

Mulvaney adamantly defended Trump, claiming the attacks have “absolutely zero to do with race.”
