The vote Friday sets up a trial in the Senate on the impeachment charges against U.S. District Judge Samuel Kent.
Kent entered a federal prison in Massachusetts Monday to serve a 33-month sentence for lying about sexually assaulting two female employees.
Kent is refusing to resign until next year so he can draw his $174,000 a year salary while in prison. If he is convicted of the impeachment charges in the Senate, he will be forced out of office and his pay will be cut off.
