Pelosi's remarks on Sunday came days before the House is expected to formally hand off articles of impeachment to McConnell, launching a weeks-long spectacle in the Senate that will almost certainly result in Trump's acquittal.

The California Democrat once again hedged on questions of timing, declining to say when House Democrat would take next steps to name their team of “managers” who will prosecute Trump in the trial.

“What I did say is that I would be consulting with my members this week,” Pelosi said, referring to a caucus-wide meeting on Tuesday morning. “We’ll determine in our meeting when we’ll send them over.”

If the House sends its slate of impeachment managers to the Senate on Tuesday, it would trigger the trial the following day, once again catapulting Trump's conduct in Ukraine to the national stage. This time, it will happen just as Democratic presidential contenders, including several sitting members of the Senate, make their final push ahead of the Iowa caucuses.

Top Democrats had waged a three-week pressure campaign against McConnell to allow new testimony from first-hand witnesses on Trump’s withholding of military aid in Ukraine. That includes former national security adviser John Bolton, who had refused to testify in the House trial but said recently he would be willing to appear before the Senate.

Pelosi's delay tactic was also intended to ramp up pressure on potential GOP swing votes: Democrats would need four Senate Republicans to call for witnesses to force McConnell's hand on the floor.

The California Democrat announced Friday that she would relent in the three-week impasse, which began Dec. 18 when she refused to formally transmit the articles across the Capitol in a bid for what she and Senate Minority Leader Chuck Schumer called a fairer process.

McConnell and his GOP allies have argued that the gambit backfired, with some Democrats in both chambers breaking with Pelosi and urging her to let the Senate begin. But the majority of Pelosi's own caucus stood behind her as she argued that McConnell was attempting to block witnesses from testifying to help acquit Trump.

Asked if she had second thoughts about delaying the articles, Pelosi responded: “No, no no, we feel that it has produced a very positive result.”
