“You have to ask the women, are they lying or not,” Mr. Reed said. “Mr. Conyers has not engaged in sexual harassment or harassment otherwise with regard to any staffer that he has had.”

He suggested that many others in Washington, including the president, would also have to resign were they to face repercussions over similar claims. President Trump himself has been accused of inappropriate sexual behavior, including harassment and assault, as have others in Congress.

“If we are talking about resignation and resignation over allegations, then half the people in the House, half the people in the Senate, including the president of the United States of America, would have to step aside, step down and or resign,” Mr. Reed said.
