State Law Enforcement division opened an investigation into Nancy Mace's sex abuse allegations. Experts say it could take a while before possible prosecution.

CHAPIN, S.C. (AP) — Rep. Nancy Mace of South Carolina on Monday used a nearly hour-long speech on the U.S. House floor to accuse her ex-fiancé of physically abusing her, recording sex acts with her and others without their consent, and conspiring with business associates in acts of rape and sexual misconduct.

The third-term lawmaker from South Carolina, who is considering a run for governor, also accused her would-be GOP rival of not investigating the allegations.
