Perdue, who serves on the Senate Budget Committee with Harris, was speaking ahead of the President’s arrival in Macon when derisively referred to the vice presidential candidate as “Ka-MAL-a (sic), Ka-MAL-a or Kamala, Kamala, Ka-mala, -mala, -mala, I don’t know, whatever,” to laughter from the crowd.

Ossoff quickly criticized Perdue for the remark, writing in a series of tweets, “My opponent, GOP Sen. David Perdue of anti-Semitic attack ad infamy, just mocked Sen. Harris’ name as ‘Kamala-mala-mala-whatever’ at a Trump rally. We are so much better than this.”

Sabrina Singh, Harris’ press secretary, condemned Perdue’s statement.

“Well that is incredibly racist,” she said on Twitter. “Vote him out and vote for @ossoff.”
