Former acting U.S. Attorney General Sally Yates testified yesterday (May 8th) before a Senate panel investigating Russian interference in the presidential election, saying that she warned the new Trump White House in January that National Security Advisor Michael Flynn, quote, "essentially could be blackmailed" by Moscow because he'd lied to his superiors about his contacts with the Russian ambassador to the U.S. She said, "To state the obvious, you don't want your national security adviser compromised with the Russians."
White House officials, including Vice President Mike Pence, had been saying that Flynn hadn't talked with the ambassador about U.S. sanctions on Russia during the presidential transition period. But Flynn Was eventually fired for lying to Pence and other officials about the nature of the calls, however, he wasn't ousted until 18 days after Yates' first warning to the White House counsel.
Yates, a career federal prosecutor who was a holdover from the Obama administration, was also fired soon after for refusing to defend Trump's travel ban. Republican senators repeatedly asked Yates yesterday about the unrelated matter of the travel ban, and about whether she'd leaked classified information, which she said she didn't.
