Sen. Lindsey Graham, who introduced a resolution condemning secretive impeachment proceedings in the House, claimed victory Monday after House Speaker Nancy Pelosi announced she’ll hold a formal vote and open up the hearings to the public.

“There is no doubt in my mind that the overwhelming response House Democrats heard from the American people and Senate Republicans in support of my resolution forced their hand,” said the South Carolina Republican, who is chairman of the Senate Judiciary Committee. “Today’s announcement is an acknowledgment of the success of our efforts last week.”
