Mike Pence has offered a rebuke of his one-time boss Donald Trump, saying history will hold him accountable for his role in the January 6 2021 attack on the US Capitol.

Pence, then the vice-president, was in the Capitol when thousands of Trump supporters breached the building in an attempt to stop Congress certifying the results of the 2020 presidential election, which Trump lost to Joe Biden.

As the vice-president has the constitutional role of Senate president, Pence was presiding over what had always been the ceremonial task of approving the votes of the electoral college.
