Joe Biden has expressed regret over his controversial comments about undecided black voters.

The former vice president made the comments Friday toward the end of his interview with The Breakfast Club host Charlamagne tha God, who encouraged Biden to go back on the show and answer more questions. Biden, the presumptive Democratic presidential nominee, suggested listeners should already have their minds made up on who they were going to vote for in November, stating: "You got more questions? I tell you what, if you have a problem figuring out whether you're for me or Trump, then you ain’t black."
