Washington (CNN) With the impeachment trial underway, senators have been listening in and taking notes as President Donald Trump's defense team and the House managers make their case. But as time goes on, senators also appear to have grown increasingly restless as they've been confined for hours to the Senate chamber -- and there have been more than a few empty seats at times during the proceedings. At various points, Republican Sens. Mitt Romney of Utah, John Barrasso of Wyoming, Tim Scott of South Carolina, and Thom Tillis of North Carolina were standing on the GOP side of the chamber, while Democratic Sens. Kamala Harris of California, Gary Peters of Michigan and Richard Blumenthal of Connecticut could be seen standing on the Democratic side.
