It is increasingly clear that there is more to know than we now know.

There is more to know about former National Security Adviser Michael T. Flynn’s activities, and who knew what about those activities and when. There is more to know about the president’s interactions with James Comey and the reason for Comey’s firing. There is more to know about the true extent of contact between Trump associates and the Russians.

Did the president have inappropriate conversations with Comey, then director of the Federal Bureau of Investigation, in an effort to exculpate himself and mitigate inquiries about Flynn?

Trump’s and Comey’s accounts, at least as they are being reported, conflict on these counts. One of these men is lying. And while I am no fan of Comey — his buzzer-beating hijinks with Hillary’s email just before the election helped hand this country over to Trump and his cabal of corruption — I am more prone to believe him than Trump, a proven, pathological liar.

The crisis isn’t limited only to Trump.

Did Vice President Mike Pence not know that Flynn was under investigation by the F.B.I. for lobbying on behalf of Turkey until “March, upon first hearing the news”? How can that be when, as The New York Times reported last week, Flynn “told President Trump’s transition team weeks before the inauguration that he was under federal investigation for secretly working as a paid lobbyist for Turkey during the campaign, according to two people familiar with the case.” Pence led the transition team.

How can Pence claim ignorance when Representative Elijah E. Cummings, ranking member of the House Committee on Oversight and Government Reform, sent Pence a letter on Nov. 18, explicitly spelling out:

“Lt. Gen. Flynn’s General Counsel and Principal, Robert Kelley, confirmed that they were hired by a foreign company to lobby for Turkish interests, stating: ‘They want to keep posted on what we all want to be informed of: the present situation, the transition between President Obama and President-Elect Trump.’ When asked whether the firm had been hired because of Lt. Gen. Flynn’s close ties to President-elect Trump, Mr. Kelley responded, ‘I hope so.’ ”

It isn’t possible Pence knew nothing. I believe Pence is a liar like his boss.

We knew that Pence was a liar when during the vice-presidential debate he repeatedly claimed that Trump had not in fact said things that he was recorded on television saying.
