First it was an intern shouting “F— You!” at the President of the United States (and keeping her job).

And now, another Hassan intern (technically a former intern) is in trouble: Arrested for “doxxing” members of the Senate Judiciary Committee, apparently hoping to get these Republicans hassled, harangued–or hurt. Politico has the story:

The U.S. Capitol Police on Wednesday arrested a 27-year-old man for posting addresses and private information of senators, according to the police department.

The department reported that it arrested Jackson A. Cosko for allegedly posting “private, identifying information (doxing) about one or more United States senators to the Internet.” Cosko has been working as an intern in the office of Democratic Rep. Sheila Jackson Lee of Texas.

Even more bizarre: Cosko snuck back into Hassan’s office to send out the “doxxing” attack.  “It was Ms. Hassan’s office that he snuck into on Tuesday — and one of her staffers that spotted him and reported him to police, leading to his arrest,” according to the police report.

The staffer chased him from the office, then called police after receiving an email threatening retaliation if the intrusion was reported, according to the police affidavit.

“If you tell anyone I will leak it all. Emails signal conversations gmails. Senators children’s health information and socials [sic],” the email read.

The police haven’t released all the information, but Cosko was arrested after someone posted the personal details (home addresses and phone numbers) of some Republican members of the Senate Judiciary Committee on Wikipedia. In particular, the information of Sens. Lindsey Graham, Mike Lee and Orrin Hatch.  The postings were apparently made during last week’s contentious hearings over Judge Brett Kavanaugh’s confirmation.

Former Hassan staffer Jackson Cosko

Cosko has been charged with making public restricted personal information, witness tampering, threats in interstate communications, unauthorized access of a government computer, identity theft, second-degree burglary and unlawful entry. And he may face more charges in the future, police say.

According to, Cosko calls himself a “Democratic Political Professional” with cybersecurity expertise.  Cosko most recently worked for Hassan as a “legislative correspondent/systems administrator,” according to Legistorm. So that’s two interns from out of Hassan’s office busted for ridiculous behavior in just the past few months. Coincidence…or something more?

At least Rep. Lee had the good sense to fire Cosko.

Hassan spokesman Aaron Jacobs said he could not comment on an ongoing investigation.
