Sen. Lindsey Graham (R-S.C.) said on Wednesday that he will reject attempts by either President Trump’s legal team or House impeachment managers to call witnesses during Trump’s Senate trial.

“I am not going to support witnesses being called for by the president. I am not going to support witnesses being called for by Sen. [Charles] Schumer [D-N.Y.],” Graham said, adding that he wants as “short a trial as possible.”

Graham’s comments come as Senate Republicans are expected to delay a decision on whether to let either side call witnesses as part of the Senate trial until after the proceeding starts in January.
