Big news from last night. National Security Advisor Mike Flynn has resigned over a controversy of a phone call with Russian Ambassador Sergey Kislyak and misleading Vice President Mike Pence on whether sanctions were discussed in that call. Then-Acting Attorney General Sally Yates (who was fired for her defiance over the Muslim ban) informed the White House that Flynn could have been compromised, vulnerable to blackmail by the Russian government. Democrats are now calling for congressional investigations, but Republicans have remained silent. The story is still developing.
