The office of Sen. Dianne Feinstein, D-Calif., has been linked to a cyber-attack on Senate Republicans during the confirmation hearings of Justice Brett Kavanaugh last fall, according to The Daily Caller.
A man was arrested in October for using allegedly using inside information to post the addresses of lawmakers that defended Kavanaugh — a cyber-attack known as doxxing
The information leak was intended to intimidate or terrorize the conservative lawmakers into submission. The suspect was also charged with witness intimidation for trying to silence a coworker.
It turns out the suspect, Jackson Cosko, was a former information technology officer for top level Democrats and is well connected to Feinstein.
Cosko "was arrested for allegedly posting the personal information (or 'doxxing') of a number of senators including Lindsey Graham, R-S.C., Mike Lee, R-Utah, and Orrin Hatch, R-Utah on Wikipedia — with information such as their home addresses and phone numbers," Fox News reported in October.
According to police, Cosko was confronted by a different Democratic senator's staffer over the alleged attack. Cosko reportedly tried to intimidate that witness into silence.
