A brief police statement did not give details, but a U.S. official said the arrest was tied to the investigation into the posting of personal information about Republican senators on the Wikipedia site as they held a hearing Sept. 27 on sexual assault allegations against Supreme Court nominee Brett M. Kavanaugh.  U.S. Capitol Police announced late Wednesday that a former junior Senate Democratic staffer has been arrested for allegedly posting private information about Republican senators on the Wikipedia Internet website.

 “It’s shocking that someone would post Senator Hatch and other Judiciary Committee Republican’s home addresses online, putting their families at risk,” Hatch’s spokesman, Matt Whitlock told the Washington Post.

 They were doxed — or had private or identifying information made public on the internet — when an anonymous Wikipedia user edited their pages. At the time, Rep. Maxine Waters (D-Calif.) rejected accusations that a member of her staff was responsible, calling them “lies, lies, and more despicable lies.” 
 
 The information posted purportedly included phone numbers and home addresses for three Republican members of the Senate Judiciary Committee at the hearing: Sen. Lindsey O. Graham (S.C.), Sen. Mike Lee (Utah) and Sen. Orrin G. Hatch (Utah). All three targeted senators were members of the Senate Judiciary Committee who questioned both Dr. Christine Blasey Ford and Kavanaugh regarding Ford’s allegations that he sexually assaulted her over 36 years ago. Jackson A. Cosko, 27, of the District, faces five federal counts including making public restricted personal information, making threats in interstate communications, identity theft, witness tampering and unauthorized access of a government computer, police said. 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 investigation will continue and additional charges may be forthcoming,” Capitol Police spokeswoman Eva Malecki said. Cosko remained in custody Wednesday evening and was due to appear before Judge Deborah A. Robinson in the U.S. District Court for the District of Columbia on Thursday.
– A former member of Democratic Sen. Maggie Hassan's staff was caught inside Hassan's Capitol Hill office Tuesday night and ultimately arrested Wednesday on charges that he "doxxed" GOP senators. Jackson A. Cosko, 27, is accused of posting "private, identifying information," including addresses, online, Politico reports. A current Hassan staffer allegedly caught him in the office and called police; he had allegedly made an unauthorized entry.

Sheila Jackson Lee; he has since been fired. A US official tells the Washington Post the arrest relates to information posted on Wikipedia during Supreme Court nominee Brett Kavanaugh's Senate Judiciary Committee hearing; during that hearing, the Wikipedia pages of Republican Sens. Mike Lee, Orrin Hatch, and Lindsey Graham were edited to include addresses, phone numbers, and email addresses, and the changes were found to be made from a Capitol Hill computer. All three are members of the Senate Judiciary Committee, Fox News reports. Cosko is charged with making public restricted personal information, witness tampering, making threats in interstate communications, unauthorized access of a government computer, identity theft, second-degree burglary, and unlawful entry.
