Trump is facing federal charges in Washington in connection with attempted election fraud and the storming of the US Capitol on January 6, 2021. If convicted, he could face decades in prison. Trump maintains his innocence in all four criminal cases and portrays the investigations against him as a politically motivated witch hunt - an attempt by Democratic incumbent Joe Biden to sideline him.
