A new phase of President Trump’s historic impeachment trial began Wednesday, with senators posing questions to the House managers and the president’s attorneys about Trump’s conduct toward Ukraine.

A key moment came when defense lawyer Alan Dershowitz suggested that a president acting in the public’s interest can’t be impeached. He then argued that a president may believe his own reelection is in the country’s best interest.

Meanwhile, debate continues outside the chamber over whether to call witnesses, including former national security adviser John Bolton. In a closed-door meeting Tuesday, Senate Majority Leader Mitch McConnell (R-Ky.) told colleagues he doesn’t yet have the votes to block witnesses.

Trump faces charges of abuse of power and obstruction of Congress. The crux of the case for his impeachment is the allegation that he withheld military aid and a White House meeting to pressure Ukraine to investigate Joe Biden and his son. Hunter Biden served on the board of Burisma, a Ukrainian energy company, while his father was vice president.
