A man accused by Congresswoman Nancy Mace of sexual abuse is hitting back at her allegations as “absolutely” false. The South Carolina lawmaker accused businessman Brian Musgrave, her ex-fiancé Patrick Bryant, and two other men of raping women and girls in their communities and taking videos of the events.

Nancy Mace (R-S.C.) is facing a defamation lawsuit filed by one of the four men she has publicly accused of sexual abuse in a floor speech, in a case that could test the legal protections members of Congress have for their official conduct.

Brian Musgrave, one of the four men Mace accused of filming acts of sexual assault in a House floor speech last month, sued Mace for libel and defamation in federal court.
