Wisconsin Senator Ron Johnson is reacting to the sexual misconduct allegations against Republican Senate candidate Roy Moore.
Moore is denying allegations he engaged in sexual activity with a 14-year-old back in the 1970s, calling them false and a "desperate political attack." Three other women were included in a Washington Post report.
"If those allegations are true, there's no way he should run for or serve on the United States Senate," Johnson told Newsline 9 in an interview Friday.
President Donald Trump also called for Moore to step aside.
Moore's election is slated for Dec. 12.
