In a letter to Democratic lawmakers Tuesday night, Pelosi hinted that she would not submit the articles nor tap House impeachment managers — who will effectively serve as the prosecution in the Senate — until McConnell publicly releases the legislation that would detail the parameters and procedures for the trial.

“Sadly, Leader McConnell has made clear that his loyalty is to the President and not the Constitution,” Pelosi wrote in the letter to colleagues. “Leader McConnell has insisted that the approach under consideration is identical to those of the Clinton trial and that ‘fair is fair.’ This is simply not true. This process is not only unfair but designed to deprive Senators and the American people of crucial documents and testimony. Under the Clinton trial, witnesses were deposed.”
