Lawmakers and administration officials sparred Sunday about the delay by House Speaker Nancy Pelosi in sending articles of President Donald Trump’s impeachment to the Senate.

The House voted on a nearly partly-line basis December 18 to impeach Trump on two counts for allegedly abusing his power. Plans for a Senate trial are on hold for now, since Pelosi hasn’t forwarded the articles, in what’s seen as an attempt to pressure Senate Majority Leader Mitch McConnell to allow witnesses. He has said he wants a quick trial.

Senator Cory Booker, a New Jersey Democrat and 2020 presidential hopeful, said Pelosi has “been a lightworker in dark times” and will do the right thing.“Those articles will come over,” Booker said on NBC’s “Meet the Press.” “What she’s just trying to do is to make sure the best possible case for a fair trial happens.”

Democrats continued to criticize a recent vow by McConnell of “total coordination with the White House” on impeachment strategy, which they say violates the Kentucky Republican’s oath of office.Durbin, the number two Senate Democrat, also chided lawmakers on both sides of the aisle for saying how they’re going to vote on Trump before the trial starts.

“I think they have gone too far,” he said. “When it comes to saying, I made up my mind, it’s all over, for goodness’ sakes, that is not what the Constitution envisioned.”Booker said that anyone in the administration who could affirm Trump’s innocence, including acting Chief of Staff Mick Mulvaney, should “come before the Senate. Swear it to an oath.”
