A PR glitch?
Joe Biden caused a stir on Friday after he told a prominent black radio host that African-Americans who back President Donald Trump "ain't black".
Inexact words: "If you've got a problem figuring out whether you're for me or for Trump, then you ain't black."
The presumptive Democratic presidential nominee quickly retracted his remark, which was interpreted by some as presuming that black Americans would vote for him.
Mr. Trump's campaign and his allies immediately seized on Mr Biden's comments. South Carolina Senator Tim Scott, a Trump supporter and the Senate's sole black Republican, said he was "shocked and surprised" by Mr Biden's remarks.
Meanwhile Trump quickly launched a website that depicts Biden as racist and himself as a conveyor of good deeds in the black community.
His campaign has doubled down on spreading insults and conspiracy theories about opponents in the wake of the president's faltering response to the coronavirus.
Mr. Biden, the presumptive Democratic nominee for the 2020 election, called into a US Black Chamber call and explained his remarks, expressing regret over being a "wise guy."
"I shouldn't have been such a wise guy. I shouldn't have been so cavalier ... I have never, ever taken the African American community for granted,"
