Senate Majority Leader Mitch McConnell (R-Ky.) said Monday that he was not ruling out testimony from new witnesses in Trump's impeachment trial, as a dispute over the rules delays preparations for the trial.

Minority Leader Chuck Schumer (D-N.Y.) wants witnesses who refused to appear during House impeachment hearings to testify in the Senate, The Associated Press reports. McConnell has declined, and House Speaker Nancy Pelosi (D-Calif.) has responded by delaying sending the Senate two articles of impeachment the House approved last week.

"We haven't ruled out witnesses," McConnell told Fox and Friends. "We've said let's handle this case just like we did with President Clinton."

Some witnesses testified in that trial, but Republicans have the votes to block anyone requested by Democrats. Harold Maass
