President Joe Biden told American voters on Friday that his presumptive election opponent Donald Trump is a threat to democracy – the day before the third anniversary of January 6th riot at the U.S. Capitol.

Trump was impeached for allegedly inciting the mob that stormed Congress to stop Biden succeeding him. Both candidates are using one of America’s darkest moments in history to rally polarized voters for what’s already a turbulent presidential election.
