Republican presidential nominee Donald Trump on Tuesday hurled a series of personal attacks at Vice President Kamala Harris, calling her “lazy” — a word long used to demean Black people in racist terms — and repeatedly questioning her intelligence and stamina.

At an event in Miami aimed at courting Latino voters, he said Harris was “lazy as hell” for not holding a campaign event. Trump’s comments ignored that Harris spent her day in meetings in Washington and recording interviews with Telemundo and NBC. He referred to the first woman of color to lead a major party ticket as “slow” and having a “low IQ.”

Later in the day during a rally in Greensboro, North Carolina, he called Harris a “stupid person” and went on to ask: “Does she drink? Is she on drugs?”

Tuesday marked the first day in more than two weeks that Harris had no public events scheduled after a run of more than 14 consecutive days of travel to political events in pivotal states, including a three-state run on Monday, starting in Pennsylvania, continuing to Michigan and ending in Wisconsin.
