Capitol Police Arrest Democratic Staffer Suspected of Doxing GOP Senators

U.S. Capitol Police have arrested a Democratic staffer suspected of posting the personal information of at least one U.S. senator to the internet.

The home addresses and other personal information of three Republican senators, Lindsey Graham of South Carolina and Mike Lee and Orrin Hatch of Utah, were posted to Wikipedia on Sept. 27 by an individual located in the House of Representatives.

Capitol Police arrested and charged Jackson A. Cosko, 27, 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, according to a police statement. Additional charges may be forthcoming as the investigation continues.

Cosko most recently worked as an intern for Rep. Sheila Jackson Lee, D-Texas. He has also worked under Sen. Maggie Hassan, D-N.H., and former Sen. Barbara Boxer, D-Calif., according to Fox News.

Jackson Lee’s chief of staff, Glenn Rushing, told Politico that Cosko has been fired.

“We’re just cooperating with law enforcement right now,” Rushing said.

[In an internet process known as "doxing," someone researches and then widely publishes private or identifiable information about an individual or organization.]

Cosko is a “Democratic Political Professional & Cybersecurity Graduate Student,” according to his LinkedIn page, which states that his job duties in the Senate included assisting senior staff “with issues before the Commerce Committee including technology, telecommunications, transportation; as well as with cybersecurity matters before the Homeland Security Committee.”

All three senators doxed Thursday sit on the Senate Judiciary Committee. Their personal information was posted online as Supreme Court nominee Brett Kavanaugh was being questioned by the committee about sexual assault allegations.

Graham said multiple people came to his house after his personal information was made public.

“I got a new number and a bunch of people beating on my door last night,” Graham told “Fox & Friends” on Sept. 28.
