Democratic congressional intern arrested for doxxing Republicans and 6 other charges

A Democratic congressional intern who worked for Sen. Dianne Feinstein, D-California and Rep. Sheila Jackson Lee, D-Texas. was arrested on Wednesday for posting the personal information of at least one Republican senator during last week’s hearing of Supreme Court nominee Brett Kavanaugh, authorities said.

U.S. Capitol Police said 27-year-old Jackson Cosko has been charged with making public restricted personal information, witness tampering, threats in interstate communication, unauthorized access of a government computer, identity theft, second-degree burglary, and unlawful entry. Police have added that the investigation is ongoing and more charges could be filed.

Senior congressional sources said that  Jackson Cosko most recently worked as an unpaid intern for Rep. Sheila Jackson Lee, D-Texas. He previously worked with Sen. Maggie Hassan, D-N.H., and former Democratic Sen. Barbara Boxer of California.

Jackson also worked or interned with the office of Sen. Dianne Feinstein, the ranking member of the Senate Judiciary Committee, as well as at least one other unnamed lawmaker.

A LinkedIn page with Jackson Cosko’s name on it describes him as a “Democratic Political Professional & Cybersecurity Graduate Student.”

Jackson Lee’s office said Cosko had only worked there for a couple of months and has now been terminated.

“It’s unfortunate,” Glenn Rushing, Jackson Lee’s chief of staff, told Fox News. Rushing added that the congresswoman’s office is “cooperating with law enforcement.”

Sen. Maggie Hassan, D-N.H. office has had two substantial personnel issues in this year. An intern for the senator shouted “Mr. President, f— you!” across the Capitol Rotunda at President Trump as he was being escorted into the office of House Speaker Paul Ryan, R-Wis. Hassan’s office declined to comment on Jackson Cosko’s arrest.

Personal information of Sens. Lindsey Graham, Mike Lee and Orrin Hatch was posted on their Wikipedia pages as the Senate Judiciary Committee questioned Kavanaugh on Thursday.

The intentional publication of the information was first caught by a Twitter bot that automatically tracks any changes made to Wikipedia entries from anyone located in the U.S. Congress and publicizes them on the social media site. The bot account later deleted the tweets because the edits contained personal information. According to the bot, whoever posted the information did so from a computer in the House of Representatives.

The home addresses of the Republican senators appeared to be correct, though the phone numbers weren’t entirely accurate. 

A “home” phone number listed for Graham appeared to direct callers to the Sexual Minority Youth Assistance League (SMYAL), a Washington D.C.-based advocacy group.

Sources told Fox News that authorities are looking into the possibility that at least two other senators were doxxed.

Fox News has also learned that Cosko was discovered by aides Tuesday night working on a computer in a Capitol Hill office that did not belong to Jackson Lee. He was arrested at his Washington home the following day. Capitol Hill security officials plan to scrub the computers in question.
