We have not talked to the former acting U.S. attorney general, but the Washington Post this evening says that before she left, longtime Atlanta legal figure Sally Yates told President Donald Trump that one of his closest White House consultants was ripe for blackmail:

The message, delivered by Sally Q. Yates and a senior career national security official to the White House counsel, was prompted by concerns that ­Flynn, when asked about his calls and texts with the Russian diplomat, had told Vice ­President-elect Mike Pence and others that he had not discussed the Obama administration sanctions on Russia for its interference in the 2016 election, the officials said. It is unclear what the White House counsel, Donald McGahn, did with the information.

Flynn resigned his post late Monday, acknowledging that he briefed Pence and others with "incomplete information" regarding his phone calls with the Russian ambassador.

"I have sincerely apologized to the President and the Vice President, and they have accepted my apology," he wrote.

Flynn will be replaced by Lt. Gen. Joseph Keith Kellogg, a U.S. Army veteran who served from 1967 to 2003.
