Democratic presidential candidate Joe Biden’s campaign has asked Facebook and Twitter to remove President Donald Trump’s posts on mail-in voting.

“Today, he has unfurled tweet after tweet pushing baseless conspiracy theories meant to discredit vote-by-mail,” campaign manager Jen O’Malley Dillon told Reuters in a statement.

“If people can go out and protest, riot, break into stores and create all sorts of havoc, they can also go out and VOTE – and keep our Election Honest,” Trump wrote earlier. “With millions of mail-in ballots being sent out, who knows where they are going, and to whom?”
