The congressional aide accused of doxxing at least three GOP senators allegedly threatened to “leak it all” if a staffer who confronted him told anyone — including the health information and social security numbers of senators’ children.
Jackson Cosko, 27, who formerly worked for Democratic Rep. Sheila Jackson Lee and Democratic Senators Dianne Feinstein, Barbara Boxer and Maggie Hassan, was arrested on Wednesday and charged with a number of criminal offenses for allegedly posting to Wikipedia the home addresses and phone numbers of GOP Senators Mike Lee, Lindsey Graham and Orrin Hatch.
The former aide was reportedly confronted by a staffer after being caught using a computer in Hassan’s office that he “was not authorized to use,” according to Fox News.
According to Capitol Police Captain Jason Bell’s sworn statement, as reported by Fox News, Cosko walked out after being confronted by the witness, who then called police. The witness then reportedly received an email from “firstname.lastname@example.org” several hours later that said, “If you tell anyone I will leak it all. Emails signal conversations gmails. Senators children’s health information and socials.”
Cosko has been charged with threats in interstate communication, publishing restricted personal information, witness tampering, identity theft, unauthorized access of a government computer, second-degree burglary and unlawful entry, according to Capitol Police.
Fox News reported that Cosko “was dressed in shorts, a t-shirt and tennis shoes and looked uneasy as Magistrate Judge Deborah Robinson detailed the seven charges against him, which carry the possibility of more than 20 years in prison.”
