The husband of a woman who worked on the campaign of former Congresswoman Katie Hill was arrested by the FBI for allegedly hacking one of her 2018 primary challengers, a report said.

Arthur Jan Dam is accused of launching cyberattacks that paralyzed the website of the political opponent, who wasn’t named in the criminal complaint, but identified himself to Politico as Bryan Caforio.

Caforio, who said he’s been cooperating with federal authorities, said his campaign spent tens of thousands of dollars to repair the site that was hacked just before a debate.

There is no evidence that Hill or Jan Dam’s wife — a former campaign staffer for the congresswoman — were involved in the scheme, prosecutors said.

The ex-California lawmaker told Politico in a statement that she was “surprised and disturbed to see the news of this criminal complaint.”

Hill said she had “no information or knowledge about any of the conduct alleged.”

Caforio lost in the 2018 primary by roughly 1,500 votes to Hill, who went on to unseat former Rep. Steve Knight, a Republican.

Hill resigned from Congress last year after a series of lewd photos of her were leaked to the media, exposing a “throuple” she had with a former female campaign staffer and her estranged husband.

The freshman lawmaker was also the target of a House Ethics Committee probe over allegations she was romantically involved with her old legislative director, which she’s repeatedly denied.
