Hacker Is Said to Have Gained Access to File With Damaging Testimony About Gaetz

An unidentified hacker has gained access to a computer file shared in a secure link among lawyers whose clients have given damaging testimony related to Matt Gaetz, the former Florida congressman who is President-elect Donald J. Trump’s choice to be attorney general, a person with knowledge of the activity said.

The file of 24 exhibits is said to include sworn testimony by a woman who said that she had sex with Mr. Gaetz in 2017 when she was 17, as well as corroborating testimony by a second woman who said that she witnessed the encounter.
