Republican presidential candidate Donald Trump questioned whether his Democratic rival Kamala Harris is “Black” during a contentious appearance at the country’s largest annual gathering of Black journalists yesterday.“Is she Indian or is she Black?” Trump said of his opponent in the presidential race, drawing a smattering of jeers. “She was Indian all the way, and all of a sudden she made a turn and became a Black person.”Harris, whose mother was Indian and whose father is Black, is the first Black and the first Asian American US vice-president.Since launching her White House campaign earlier this month, Harris has faced a barrage of sexist and racist attacks online, while Republican Party leaders have urged lawmakers to refrain from personal attacks and focus on her policy positions.The interview — in front of a gathering of about 1,000 journalists — started on a tense note, when ABC News reporter Rachel Scott asked Trump to explain why Black voters should support him despite a history of racist comments.In response, Trump called the question “horrible,” “hostile” and a “disgrace” and described ABC as a “fake” network.“I have been the best president for the Black population since Abraham Lincoln,” he said.Trump’s first-ever appearance at the National Association of Black Journalists’ annual convention in Chicago received a backlash from some members, prompting a co-chair of the convention to step down in protest.
