The U.S. Department of Justice has opened an investigation into Republican U.S. Representative Cory Mills of Florida, according to a person familiar with the matter. The specifics of the Justice Department's probe remain undisclosed.

Mills, who was first elected to Congress in 2022, has been under investigation by the bipartisan House Ethics Committee for two years. The committee is examining allegations including campaign finance violations, misuse of congressional resources, and sexual misconduct. Mills has denied all allegations of wrongdoing.

Separately, Mills has faced accusations of assault and threats. In a 2025 police report, his then-girlfriend, Sarah Raviani, accused him of grabbing, shoving, and pushing her out of his apartment. Mills denied this accusation, calling it "patently false." Raviani later stated to the Daily Mail that while the matter was "emotionally charged," there was no physical altercation, and her decision to involve authorities was influenced by jet lag, sleep deprivation, and alcohol consumption.

Last year, Lindsey Langston, Miss United States 2024, filed a sheriff's report alleging Mills threatened her. Langston, a Florida Republican state committee member, claimed she had a romantic relationship with Mills from November 2021 to February 2025. She stated that Mills threatened to release nude images and videos of her and to harm any men she intended to date. Mills has called these claims "false and misrepresent the nature of my interactions."

Republican Congresswoman Nancy Mace of South Carolina has called for Mills to be stripped of his responsibilities. Mills, in a past interview, distinguished himself from former Representative Eric Swalwell, who resigned amid sexual misconduct allegations, stating he had never sexually harassed staffers or interns and that the accusations against him were a "political, Democratic tit-for-tat."

Mills' divorce proceedings are reportedly ongoing, and his longtime chief of staff and chief counsel, Catherine Treadwell, resigned earlier this month. The House has a high bar for expelling members, requiring a two-thirds vote, with only six members having been expelled in history.
