Jackson Cosko Biography – Jackson Cosko Wiki
Jackson Cosko is a former Democratic Senate staff member sentenced to four years in prison for a burglary and hacking campaign that culminated in the single largest known theft of electronic data from the Senate and the posting of private information about Republican senators on the Internet.
The information posted on the Wikipedia site purportedly included phone numbers and home addresses for three Republican members of the Senate Judiciary Committee at the hearing: Sen. Lindsey O. Graham (S.C.), Sen. Mike Lee (Utah) and Sen. Orrin G. Hatch (Utah).
In April, Jackson Cosko pleaded guilty to five felonies, admitting that after being fired last year from his work as a systems administrator on Hassan’s staff, he repeatedly used a colleague’s key to enter the office, install keylogging equipment that stole work and personal email passwords, and downloaded a massive trove of data from Senate systems.
Jackson Cosko also acknowledged that after growing angry about the GOP’s handling of the Supreme Court nomination, he released home addresses and phone numbers of Sens. Lindsry Graham, Orrin Hatch, and Mike Lee on Wikipedia. After initial press coverage of that doxing, Cosko released information about Majority Leader Mitch McConnell and Sen. Rand Paul.
Shortly before the sentence was handed down, Cosko stood at a courtroom lectern and apologized. In his two-minute statement to the court, Cosko said that he’d been struggling with substance abuse and mental health issues and that the judge’s decision earlier this year to let him enter a treatment program was pivotal.
Jackson Cosko faced five federal counts including making public restricted personal information, making threats in interstate communications, identity theft, witness tampering and unauthorized access of a government computer. He also faced District charges of second-degree burglary and unlawful entry.
Jackson Cosko worked for U.S. Sen. Maggie Hassan (D-NH) and previously worked for Sen. Barbara Boxer (D-CA). He previously worked or was an intern with the office of Sen. Dianne Feinstein, D-CA. A September 2018 letter from Sheila Jackson Lee (D -TX) identified him as a staffer for her office at that time. Rep. Sheila Jackson Lee is a member of the U.S. House Judiciary Committee.
