An amazing read by The Washington Post, detailing two months of talks and debates between two administrations leading up to tonight’s resignation:

After the sanctions were rolled out, the Obama administration braced itself for the Russian retaliation. To the surprise of many U.S. officials, Russian President Vladimir Putin announced on Dec. 30 that there would be no response. Trump praised the decision on Twitter.

Intelligence analysts began to search for clues that could help explain Putin’s move. The search turned up Kislyak’s communications, which the FBI routinely monitors, and the phone call in question with Flynn, a retired Army lieutenant general with years of intelligence experience.

From that call and subsequent intercepts, FBI agents wrote a secret report summarizing ­Flynn’s discussions with Kislyak.

Yates, then the deputy attorney general, considered Flynn’s comments in the intercepted call to be “highly significant” and “potentially illegal,” according to an official familiar with her thinking.

Seriously. Read that entire piece.
