A Democratic congressional aide accused of publishing the private information of at least three Republican lawmakers allegedly threatened to leak senators’ children’s health information if a witness told anyone about his activities.
Jackson Cosko, who recently worked for Rep. Sheila Jackson Lee, D-Texas, 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. Graham, Lee and Hatch’s information was published on Thursday.
According to a sworn statement by Capitol Police Captain Jason Bell, a witness Tuesday saw Cosko at a computer in a senator’s office, where he used to work, a day after two other unnamed senators’ information had been put on Wikipedia. Cosko worked for other Democratic senators including Sen. Dianne Feinstein, D-Calif., Sen. Maggie Hassan, D-N.H., and former Sen. Barbara Boxer, D-Calif. While earlier reports identified Cosko as an intern for Jackson Lee, his lawyer said that he was working as a fellow in her office, paid by an outside institution.
Sources familiar with the case tell Fox News Cosko was in Sen. Hassan’s office, where he was not authorized to be and was caught using a login he was not authorized to use. Cosko earlier was let go by Senator Hassan’s office. A spokesman for Hassan says she “strongly denounces the alleged actions.”
According to Bell’s statement, Cosko is alleged to have been confronted by the staffer and then walked out. The staffer then called police. Hours later the witness received an email from “firstname.lastname@example.org” saying: “If you tell anyone I will leak it all. Emails signal conversations gmails. Senators children’s health information and socials.”
“Socials” apparently referred to social security numbers, while Signal is a secure messaging application. Bell said that there was probably cause to believe that Cosko published the information of senators, and then made threatening statements directed to the unnamed witness “with the intent to hinder, delay, or prevent” the witness from reporting it to authorities.
Cosko’s defense attorney, Brian Stolarz, told Fox News his client acted alone.
“We all need to take a deep breath,” said Stolarz. “In this political climate everyone wants to jump to conclusions. We need to put the conspiracy theories aside and focus on the allegations. Jackson Cosko is innocent until proven guilty, and we intend to challenge the charges.”Cosko is charged with publishing restricted personal information, threats in interstate communication, unauthorized access of a government computer, identity theft, witness tampering, second degree burglary, and unlawful entry. The complaint says that five senators were doxxed. Fox News learned Wednesday that Capitol Hill police were investigating additional doxxing incidents, including one involving Sen. Rand Paul, R-Ky.
