Five Trump associates have now pleaded guilty or been charged with crimes in Russia-related or spinoff investigations. Cohen pleaded guilty in NY, saying he and Trump had arranged the payment of hush money to porn star Stormy Daniels and a former Playboy model to influence the election.

"If there's evidence that the president should be impeached, let that emerge", said House Minority Leader Nancy Pelosi.
"The developments of today will permit us to have the stay lifted in the civil case & should also permit us to proceed with an expedited deposition of Trump under oath about what he knew, when he knew it, and what he did about it", Avenatti tweeted.
Those prosecutors scrambled to get a plea deal done to avoid appearances that news of it could influence the midterm elections.
