Republican leaders are warning party members against using overtly racist and sexist attacks against Vice President Kamala Harris, as they and former President Donald Trump ‘s campaign scramble to adjust to the reality of a new Democratic rival less than four months before Election Day.

At a closed-door meeting of House Republicans on Tuesday, National Republican Congressional Committee chairman Richard Hudson, R-N.C., urged lawmakers to stick to criticizing Harris for her role in Biden-Harris administration policies.

“This election will be about policies and not personalities,” House Speaker Mike Johnson told reporters after the meeting.

“This is not personal with regard to Kamala Harris,” he added, “and her ethnicity or her gender have nothing to do with this whatsoever.”
