According to a sworn written statement that has been obtained by the Ethics committee, a woman says that in summer of 2017, when she was 20 years old, she attended a party in Florida that Gaetz also attended, which featured alcohol and drugs including cocaine and MDMA, sources familiar with the committee's work told ABC News.

In the sworn statement, which has not been previously reported, the woman said that in addition to Gaetz, the party was attended by the then-minor who was at the center of a yearslong Justice Department investigation into accusations that the Florida Congressman had sex with her when she was 17, according to sources.

According to the statement provided to the committee, sources said the woman who made the statement -- who ABC News is not identifying -- said she saw the then-minor naked at the party, which was also attended by adult men other than Gaetz, and that at the party there allegedly were bedrooms that were made available for sexual activities.
