“Senate Minority Leader Chuck Schumer proposed calling former national security adviser John Bolton and acting White House chief of staff Mick Mulvaney as witnesses at an impeachment trial for President Trump in a letter to Senate Majority Leader Mitch McConnell on Sunday,” NBC News reports.

“The offer is intended as a signal that Democrats are seeking an evidentiary trial, not intending to simply rely on the House investigation.”

BREAKING NEWS: Schumer’s proposal to McConnell. If he rejects these reasonable ground rules & insists on a non-trial, the House should consider treating that as a breach of the Senate’s oath & withholding the Articles until the Senate reconsidershttps://t.co/a9zbBywFBG
