The White House and Republicans pushed back on Monday at Sen. Chuck Schumer’s proposal to call witnesses — including former national security adviser John Bolton and acting chief of staff Mick Mulvaney — to testify at President Trump’s expected impeachment trial in the Senate.

“Let us hope that fairness will prevail” a laughable quote from @SenSchumer this AM….after the dems release an ‘impeachment report’ in the middle of the night,” White House press secretary Stephanie Grisham wrote on Twitter. “Thankfully the people of this country continue to see the partisan sham that this is.”

Sen. John Cornyn (R-Texas), who would serve as a juror in the Senate impeachment trial against Trump, said Democrats had their chance to call Bolton and Mulvaney during their investigation in the House that led to two articles of impeachment — for abuse of power and obstruction of Congress.

“He should have talked to Schiff, Nadler, and Pelosi. They dropped their demands for this testimony when it became apparent that witnesses were going to seek court guidance on competing demands. Schiff dropped the ball,” Cornyn wrote on Twitter, referring to Reps. Adam Schiff and Jerrold Nadler and House Speaker Nancy Pelosi, who spearheaded the impeachment inquiry in the House.

A spokesman for Senate Majority Leader Mitch McConnell (R-Ky.), who has been coordinating with the White House on conducting a possible impeachment trial, said the two leaders are expected to meet.

“Leader McConnell has made it clear he plans to meet with Leader Schumer to discuss the contours of a trial soon,” spokesman Doug Andres said. “That timeline has not changed.”

Schumer sent McConnell a letter late Sunday, urging him to conduct a “fair and honest” trial and suggesting he subpoena Robert Blair, an aide to Mulvaney, and Michael Duffey, a White House budget official, along with Mulvaney and Bolton.

The House Judiciary Committee last Friday approved the articles of impeachment, and the full Democrat-controlled House is expected to vote on the charges as early as Wednesday.

If they are approved, the scene would then shift to a trial in the Senate, where Republicans hold 53 of the 100 seats.

In his letter, which began the negotiations between Democrats and Republicans, Schumer proposed beginning the trial on Jan. 6 with the swearing in of Chief Justice John Roberts to preside over the proceedings.

The New York Democrat noted that the four witnesses he listed were asked to testify in the House inquiry, but did not appear, at the behest of the White House.

Bolton listened in on the July 25 phone call in which Trump asked Ukrainian President Volodymyr Zelensky to launch an investigation into political rival Joe Biden and his son Hunter, who worked for a Ukrainian energy company.

Democrats say Trump used $391 million in US military aid to Ukraine as leverage.

Mulvaney heads up the White House budget office that suspended the aid package.
