At 11:30 am today, Sally Yates will begin testimony before the Senate committee that's investigating Russian meddling in the US presidential election.

Who's Sally Yates again?

She was a deputy attorney general in the Obama administration, then she was Acting Attorney General for a while at the request of President Donald Trump, and then, after 10 days on the job, she was fired by Trump for refusing to defend his first travel ban.

Oh, also: weeks before Trump then got around to firing Michael Flynn, his Russia-hugging national security adviser, Yates, while still on the job, had warned the White House that Flynn had been misleading the administration about his conversations with the Russian ambassador—and was therefore vulnerable to Russian blackmail.

It took quite a while for Trump to act on this information, and it's taken a long time for Yates to testify. She was originally going to testify in front of the House committee investigating Russian meddling, but that testimony was cancelled by the committee's Republican chairman, Devin Nunes (who has since resigned from the investigation after a lot of other drama).

But now it's happening, and perhaps the most exciting thing about today's testimony is that we're finally going to hear from someone who's not beholden to Team Trump—but was on the inside of the Flynn drama, and clearly has a story to tell. Here's the livestream:

PS: Obama reportedly warned Trump about Flynn months before Trump was even sworn in to office.
