"As Trump’s No. 2 and as head of the transition team, Pence has increasingly found himself drawn into the widening Russia investigation.
Pence — along with Attorney General Jeff Sessions, Kushner, Chief of Staff Reince Priebus and White House Counsel Donald McGahn — was one of the small group of senior advisers the president consulted as he mulled his decision to fire Comey, which is now a focus of Mueller’s investigation.
He also was entangled in the events leading up to the dismissal of Michael Flynn, Trump’s former national security adviser, who originally misled Pence about his contact with Russian officials — incorrect claims that Pence himself then repeated publicly.
The vice president was kept in the dark for nearly two weeks about Flynn’s misstatements, before learning the truth in a Post report. Trump ultimately fired Flynn for misleading the vice president."
