House Speaker Nancy Pelosi (D-Calif.) announced on Tuesday, Jan. 14, that the House will take up a resolution appointing impeachment managers on Wednesday, a move allowing the chamber to transmit the articles of impeachment against President Donald Trump to the Senate to start a trial.

“Tomorrow, we will transmit those articles & name impeachment managers. The Senate must choose between the Constitution & a cover-up,” Pelosi tweeted.

In an attached statement, Pelosi said, “The American people deserve the truth, and the Constitution demands a trial. The House will now proceed with a vote on transmitting the articles of impeachment and naming impeachment managers on Wednesday, January 15. The president and the senators will be held accountable.”

The House speaker has not named the impeachment managers, but Adam Schiff and Jerry Nadler—chairmen of House Intelligence and Judiciary committees respectively —are expected to be two of them, ABC News reported.

CNN called Pelosi’s announcement on the House vote “a stark concession that her plan to delay that action for nearly a month failed.”

According to CNN, when Pelosi refused to transmit the impeachment articles to the Senate after the House passed them in mid-December, she explained, “The next thing for us will be when we see the process that is set forth in the Senate, then we’ll know the number of managers that we may have to go forward and who we will choose.”

With such a move, Pelosi wanted to use her possession of the articles to pressure Senate Majority Leader Mitch McConnell (R-Ky.), notably on the issue of witness requests in the Senate trial.

But McConnell replied earlier this month, “The House Democrats’ turn is over,” and “There will be no haggling with the House over Senate procedure.” McConnell announced he secured enough support from Republican colleagues to begin the trial without making a commitment on witnesses.

The leverage Pelosi imagined she possessed to get McConnell to accede to her wishes did not exist, CNN saidn.“The move she announced Tuesday is the equivalent of throwing her hand in, understanding that what she was holding was, in a word, dreck,” the news network wrote.

Following Pelosi’s announcement, McConnell said that the Senate trial is likely to begin next Tuesday, Jan. 21.

“We’ll be able to go through some preliminary steps here this week, which could well include the Chief Justice coming over and swearing-in members of the Senate and some other kind of housekeeping measures…which would set us up to begin the actual trial next Tuesday,” said McConnell.
