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. In Hill’s FEC records, she lists a $500 in-kind contribution from Dam on March 25, 2018, for “Graphic design and website security consultation.”
