A Democratic Capitol Hill staffer, who was arrested last week for allegedly doxxing several prominent Republican senators, may have been planning more attacks, prosecuting attorneys have revealed.
Jackson Cosko was denied bond in a hearing Tuesday, The Washington Times reports. A D.C. judge determined Cosko was a “threat to the community” after prosecutors revealed further details of Cosko’s arrest and subsequent searches made of his home, storage unit, and car.
Cosko was arrested last week after authorities discovered he was behind a series of “doxxing” attacks; Cosko allegedly posted the private addresses and phone numbers of several GOP senators who serve on the Senate Judiciary Committee. The information appeared on each senator’s Wikipedia page almost immediately after Sen. Lindsey Graham (R-SC) concluded a fiery indictment of Democrat behavior during a hearing on sexual assault allegations leveled at now-Supreme Court Justice Brett Kavanaugh.
A bot, which monitors edits made to Wikipedia from Congressional computers, caught the changes immediately. It took only a few days for investigators to track the changes back to Cosko.
In court Tuesday, investigators revealed that a fellow Democratic staffer, who recognized Cosko from his time spent working for Sen. Maggie Hassan (D-NH), reported Cosko for “breaking into” Hassan’s office and using a staff computer without authorization.
After being discovered and ousted from the office, Cosko allegedly sent the Hassan staffer who recognized him a series of threatening messages, claiming he had more “sensitive information” that he could release at will.
When investigators searched Cosko’s home, they reportedly found both cocaine and methamphetamine, drug paraphernalia, a “variety of computers, phones, and tablets,” a number of video game systems, and stationery stolen from Sen. Hassan’s office.
In Cosko’s car and storage unit, law enforcement officials allegedly found “plans to target other lawmakers, and also found notes he had written to himself laying out a checklist for trying to get rid of the evidence of his activities.”
Cosko will remain in custody until his trial. He’s also been fired from the offices of Rep. Sheila Jackson Lee (D-TX), where he served as a “fellow.” Initially Lee called Cosko an “intern,” but it has since been revealed that Cosko was being paid to serve in Lee’s office by an “outside organization,” and that Lee trusted him with official communications made on her behalf.
