The terms will ultimately be set by Senate Majority Leader Mitch McConnell (R-Ky.) and Minority Leader Chuck Schumer (D-N.Y.). The two will need to reach an agreement on the parameters of the trial — including the time frame, witness testimony and obtaining documents — that will require 51 votes. Democrats have questioned the impartiality of the Senate trial after McConnell said he’s coordinating with the White House on strategy.

Pelosi blamed McConnell for the impasse, saying he was the one who wasn't abiding by precedent set during President Bill Clinton's impeachment trial in 1998.

"They had a bipartisan bill with 100 senators voting for it, that’s the precedent. That’s not what McConnell was saying," Pelosi told POLITICO. "But let’s give them the chance to do what they have to do over there. And so until they do, there’s really not that much to talk about."

In her weekly press conference earlier Thursday, Pelosi essentially dismissed the idea that she would hold onto the articles of impeachment indefinitely.

“We’re ready,” Pelosi told reporters Thursday about moving forward after the House impeached Trump, charging him with abuse of power and obstruction of Congress. “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."

The California Democrat's comments came after widespread confusion within the Democratic Caucus when Pelosi wouldn’t commit to sending the articles of impeachment to the Senate, saying she was concerned the upper chamber wouldn’t hold a fair trial. She made her initial statements in a press conference late Wednesday night just minutes after the House took the historic step of impeaching Trump.

The speaker, who refused to entertain many questions on the Senate trial during her weekly press conference, said she was merely reiterating what she had said the night before. But internal conversations among lawmakers and staff about the California Democrat’s Wednesday night comments reflected uncertainty about the post-impeachment process.

Some in the caucus interpreted it to mean Pelosi might refuse altogether to send articles to the Senate and prevent the Senate from holding a trial, an idea hatched by prominent liberal lawyers. But senior aides suggested that Democrats would deliver the articles early next year when Congress returns in early January, though did not offer specifics.

Pelosi reiterated on Thursday that she would demand a “fair trial” in the Senate, but again declined to say what that would look like.

Schumer and Pelosi met late Thursday morning and the Senate Democratic leader said he planned to meet with McConnell in the afternoon.
