Trump called aides hours before Capitol riot to discuss how to stop Biden victory

Sources tell Guardian Trump pressed lieutenants at Willard hotel in Washington about ways to delay certification of election result

Hours before the deadly attack on the US Capitol this year, Donald Trump made several calls from the White House to top lieutenants at the Willard hotel in Washington and talked about ways to stop the certification of Joe Biden's election win from taking place on 6 January.

The former president first told the lieutenants his vice-president, Mike Pence, was reluctant to go along with the plan to commandeer his largely ceremonial role at the joint session of Congress in a way that would allow Trump to retain the presidency for a second term.
