Rep. Katie Hill addressed supporters in a video posted to her campaign’s YouTube account, for the first time since announcing her resignation Sunday. Hill, D-Calif., said that she will “fight to ensure no one else has to live through what [she] just experienced.”

She said that her decision to step down from her seat after being the victim of what she characterized as “electronic assault” or “digital exploitation,” noting that some call it “revenge porn,” has been the “most difficult decision” of her life.

The resignation comes after a British tabloid and a conservative blog posted intimate pictures of Hill and allegations that she had been involved with a campaign staffer and a separate congressional staffer. Hill admitted to and apologized for the relationship with the campaign staffer on Wednesday. She denies the relationship with the congressional staffer, which the House Ethics Committee opened an inquiry into last week.
