Biden says Trump should carry weight of US Capitol riot 'to his grave' in new book

Former US President Joe Biden has unleashed a barrage of criticism on President Donald Trump in a soon-to-be released memoir, saying he believes the Capitol riot on 6 January 2021 "should follow him to his grave".

In an excerpt published in The Atlantic on Monday, Biden also said Trump should not have pardoned supporters who stormed Congress in a bid to thwart the certification of Biden's election victory.

"The criminals who attacked law-enforcement officers that day didn't deserve pardons," the former president wrote. "They deserved prison terms."

White House spokesperson Lauren Bis called Biden "the worst president in American history" in response to the BBC's request for comment.
