The House is expected to vote Wednesday to send the articles of impeachment against President Donald Trump to the Senate.

Speaker Nancy Pelosi met privately Tuesday at the Capitol with her Democratic caucus to discuss the timetable. Meanwhile, Senate Majority Leader Mitch McConnell opened the Senate on Tuesday scoffing at the House's “bizarro” impeachment strategy.

"I am proud of the moral courage of Members to honor the vision of our Founders for a Republic, the sacrifice of our men and women in uniform to defend it and the aspirations of our children to live freely within it," Pelosi said in a statement.

She also admonished McConnell in her statement, saying his dismissal resolution was "a coverup." "The American people will fully understand the Senate’s move to begin the trial without witnesses and documents as a pure political cover-up.  Leader McConnell and the President are afraid of more facts coming to light, she said."

He meets later with Republican senators on terms of the trial. Trump is charged with abuse of power for pushing Ukraine to investigate Democratic rival Joe Biden as he withheld aid to Ukraine. Trump is also charged with obstructing Congress' probe.

It will be only the third presidential impeachment trial in American history. Trump has denied any wrongdoing.
