After a more than eight-hour hearing Wednesday with four constitutional scholars, House Judiciary Committee Chairman Jerrold Nadler (D-N.Y.) said President Trump’s conduct with Ukraine rose to an impeachable offense.

“I will honor my oath, and as I sit here today, having heard consistent, clear and compelling evidence that the president has abused his power, attempted to undermine the constitutional role of Congress, and corrupted our elections, I urge my colleagues to stand behind the oath you have taken,” Nadler said at the conclusion of the hearing. “Our democracy depends on it.”

Three law professors who testified were summoned by the Democrats, while another was tapped by Republicans. The GOP-picked witness cautioned against moving too quickly with impeachment, while the other three argued that Trump’s behavior is impeachable.

The inquiry has moved into a new phase after the House Intelligence Committee voted along party lines Tuesday to approve a 300-page report that concluded Trump had “compromised national security to advance his personal political interests.”

At the heart of the Democrats’ case is the allegation that Trump tried to leverage a White House meeting and military aid, sought by Ukraine in the face of Russian military aggression, to pressure President Volodymyr Zelensky to launch investigations of former vice president Joe Biden and his son Hunter, as well as an unfounded theory that Kyiv conspired with Democrats to interfere in the 2016 presidential election.
