The call came a day after the Texas congressman admitted to an extramarital affair with an aide, and as he faced a runoff to keep his seat.

The physical struggle, involving Senator Tim Sheehy of Montana, was captured on video. The protester, Brian McGinnis, said on social media that his arm was broken.

Prosecutors called more than 30 witnesses, including 11 women who said the three men had sexually abused them. The brothers, who have pleaded not guilty, face life in prison if convicted.
