One thing that Marc Kasowitz (President Trump's personal attorney) said at his press statement was this:

"Although Mr. Comey testified he only leaked the memos in response to a tweet, the public record reveals that the New York Times was quoting from these memos the day before the referenced tweet, which belies Mr. Comey's excuse for this unauthorized disclosure of privileged information and appears to entirely retaliatory. "

It appears Comey lied because he told Sen. Collins that it was AFTER Trump's tweet that he needed to get the memos out.  If, in fact, the New York Times had already quoted from the memos THE DAY BEFORE Trump's tweet, then Comey LIED UNDER OATH.

If Comey LIED UNDER OATH, will he be arrested and charged?
