"We haven't seen as many of the sex scandals with women," Hill said in an exclusive interview that aired on "Good Morning America."
The House Ethics Committee announced in October 2019 that it would investigate Hill, who represented California's 25th congressional district, for allegedly having a sexual relationship with one of her congressional staffers. She continued to deny the allegation.
The 25th District includes the cities of Santa Clarita, Simi Valley Palmdale, Lancaster and part of the San Fernando Valley.
The alleged relationship would have been a violation of House rules that were established in February 2018 following the #MeToo movement.
Hill has admitted to - and apologized for - having a relationship with a campaign staffer when she was running for Congress in 2018. That relationship was not covered by House rules since Hill was not a member of Congress at the time.
During the interview, Hill told ABC News' George Stephanopoulos it was "absolutely" her biggest mistake to have a relationship with a campaign staffer.
