The Katie Hill campaign has been in the eyes of the FBI for a few years now. With that said, Federal agents have recently arrested a hacker, Arthur Dam.
He was associated with Hill during the hacking spree as she ran in the 2018 Democratic California primary. That gave the delinquent the nomination.
Many other Democrats running in the primary were hacked except Hill. That, of course, became quite suspicious enough for the FBI to investigate. So because of the extra attention (in not such a good way), she ended up resigning from the primary.

According to The Intercept:
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.
