The woman who was at the center of a yearslong Justice Department investigation into sex trafficking allegations surrounding Rep. Matt Gaetz testified to the House Ethics Committee that the now-former Florida congressman had sex with her when she was 17 years old, sources familiar with the investigation told ABC News. President-elect Donald Trump announced Wednesday that Gaetz had been tapped to serve as attorney general, overseeing the very branch of government that previously conducted its own investigation of him, which ended last year without charges being brought. Gaetz resigned from office following Trump's announcement. This came as the House Ethics Committee was in the final stages of its investigation, said sources, who added that the committee was preparing to meet this week to deliberate over whether to release a final report on the matter.
