BREAKING: Nancy Pelosi Unveils 7 Impeachment Managers For President Trump Senate Trial

The Senate is poised to launch into an impeachment trial for President Trump as early as next Tuesday, Majority Leader Mitch McConnell, R-Ky., said, as warring factions on Capitol Hill ended an impasse that had left the entire process in limbo for nearly four weeks.

The GOP leader, in remarks to reporters Tuesday, also shot down the notion -- floated by the president but later amplified by Democrats -- that the Senate could vote to dismiss the case. And he warned those calling for new testimony that Republicans could have the chance to call witnesses, too, as he set expectations for proceedings to start in the coming days and formally launch next week.

“We will be able to go through some preliminary steps this week … which would give us the ability to start the actual trial next Tuesday,” McConnell told reporters, while once again stating that he has the votes to pass the so-called "organizing resolution" that would lay out the framework for the trial.

“All 53 of us have reached an agreement,” he said, referring to Republican members.

McConnell spoke to reporters after House Speaker Nancy Pelosi, D-Calif., announced that the lower chamber would vote to transmit the articles of impeachment to the Senate on Wednesday. They are doing so without assurances from McConnell that he’ll allow for witnesses and documents in the trial, despite Democrats holding up the process for the past month in pursuit of such a commitment.
