Federal agents have arrested Arthur Dam in connection with a hacking spree that disrupted the 2018 Democratic California primary that ultimately nominated Katie Hill, according to a new criminal complaint.
“Dam was found to be connected to the cyber attacks through subscriber information, IP addresses, geolocation history, and open sources, including through his employer and his wife, K.O., who worked for one of the Victim’s opponents,” the complaint reads.
Dam’s wife is Kelsey O’Hara, Hill’s fundraiser during the campaign and her district director after she won office. O’Hara was also the subject of a sexual remark made by Hill and caught on tape by Vice News in 2018. In Hill’s Federal Election Commission records, she lists a $500 in-kind contribution from Dam on March 25, 2018, for “graphic design and website security consultation.”

During the campaign, the websites of Hill’s opponents, Democrats Jess Phoenix and Bryan Caforio, who was supported by Justice Democrats, were both attacked, though Hill’s never was, raising suspicions at the time that Hill’s campaign was behind them. One major attack on Caforio’s campaign website came at a crucial moment, just an hour before the biggest debate of the primary, the complaint notes. Hill eventually won the California primary by fewer than 3,000 votes.
Hill’s campaign was the subject of unusual national attention during her campaign, including a Vice News documentary and a Rolling Stone article. On March 3, the 25th Congressional District will hold a special election to replace Hill, who resigned in October 2019.
