Sen. Ron Wyden (D-OR) just pulled Vice President Mike Pence into the heart of the Russia investigation, asking former FBI Director James Comey whether Pence was aware of the concerns about Mike Flynn's Russia connections both prior to and during his brief tenure in the administration—that is during the transition. Which Mike Pence directed.
Comey: "My understanding is that he was."
That undermines Pence's claim that he was totally ignorant of Pence's Russia ties and that Flynn had lied to him about it. That supposed lie, remember, was the justification Trump gave for firing Flynn.
