A committee source told The Independent on Monday that the select committee has not been in contact with Mr Pence and would not say whether the former vice president would be receiving a subpoena or request for him to voluntarily give evidence anytime soon.

But according to sources familiar with both the select committee’s work and the workings of Mr Pence and his inner circle, the man who Trumpist rioters targeted with a hangman’s noose may already be on board with the investigation into whether his former boss knew what would happen at the Capitol one year ago.

Though the former vice president has not been asked to give evidence, voluntarily or otherwise, sources tell The Independent that the select committee has conducted more than one interview with Mr Short, who served as Mr Pence’s chief of staff from 2018 until he left office on 20 January last year.
