 A man accused of "doxing" several GOP senators was caught on Tuesday night inside the office of Sen. Maggie Hassan by a Hassan staffer, who then called the police on the man, according to a person familiar with the matter. 
 
 The U.S. Capitol Police on Wednesday arrested Jackson A. Cosko, 27, for posting addresses and private information of senators, according to the police department. A former Hassan (D-N.H.) staffer, Cosko made an unauthorized entry into her Capitol Hill office on Tuesday evening which led to his arrest, the person familiar with the matter said.

 Hassan's office declined to comment. Cosko most recently worked for Hassan as a “legislative correspondent/systems administrator,” according to Legistorm. Cosko left Hassan’s office in May. Cosko is due in U.S. District Court for the District of Columbia on Thursday. 
 
 The department reported that it arrested 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 and has been fired, according to her chief of staff, Glenn Rushing. 
 
 “We’re just cooperating with law enforcement right now,” Rushing said in an interview. 
 
 Cosko graduated from The George Washington University in 2014 and previously worked for Hassan and California Democratic Sen. Barbara Boxer, who has since retired. 
 
 Last week, the Wikipedia pages of Sens. Mike Lee of Utah, Orrin Hatch of Utah and Lindsey Graham of South Carolina were altered to show their addresses, phone numbers and email address. The information was posted during an extraordinary hearing in which Supreme Court nominee Brett Kavanaugh and Christine Blasey Ford testified about Ford’s accusation that Kavanaugh sexually assaulted her in 1982. All three are GOP senators who are supportive of Kavanaugh. 
 
 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. A bot that tracks edits to Wikipedia pages found that the changes were made from a computer on Capitol Hill on the House side. 
 
 “The investigation will continue and additional charges may be forthcoming,” the police 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. ||||| 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. 
 
 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. 
 
 Cosko also faces District charges of second degree burglary and unlawful entry, police said. He is set to appear before U.S. Magistrate Deborah A. Robinson of the District on Thursday afternoon, the U.S. attorney’s office for the District said. 
 
 “The investigation will continue and additional charges may be forthcoming,” Capitol Police spokeswoman Eva Malecki said. 
 
 Cosko could not immediately be reached for comment. 
 
 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. 
 
 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).

 They were doxed — or had private or identifying information made public on the internet — when an anonymous Wikipedia user edited their pages. The information was quickly removed after the doxing was discovered and aides contacted authorities. 
 
 Edits to the online encyclopedia were traced to IP addresses of computer devices assigned to the U.S. Capitol. Waters in her statement last week said Capitol Police and internal computer specialists determined that an IP address cited online did not belong to her office or anyone on her staff. 
 
 According to the Legistorm website of congressional disclosures, Cosko was employed as a low-level aide from January 2017 to May 2018 with the office of U.S. Sen. Maggie Hassan (D-N.H.), and earlier with former senator Barbara Boxer (D-Calif.). 
 
 Hassan spokesman Aaron Jacobs said he could not comment on an ongoing investigation. 
 
 Cosko was paid $23,000 over six months ending March 31, according to Legistorm. 
 
 A LinkedIn website to a Jackson Cosko lists work from Jan. 2016 to May 2018 as an intern, press assistant and legislative correspondent/systems administrator assisting senior Senate staff on matters before the commerce and homeland security committees, including cyber security issues. 
 
 It could not be immediately determined if Cosko had any past connection to Waters’ office. The office did not immediately respond to a request for comment late Wednesday. ||||| Personal information of Republican Sens. Lindsey Graham, Mike Lee and Orrin Hatch were posted by an unknown person located in the House of Representatives on Thursday during the hearing of Supreme Court Nominee Judge Brett Kavanaugh. 
 
 The information, which supposedly included home addresses and phone numbers, was posted - or doxxed - on the senators’ respective Wikipedia pages, where users are allowed to update the information at any time. The information has since been removed. 
 
 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. The leaking of information occurred sometime after the three lawmakers questioned Kavanaugh.

 But while the home addresses of the senators appear to be correct, the phone numbers weren’t entirely accurate, with most either disconnected or going to voicemail. 
 
 A “home” phone number listed for Graham appears to direct the callers to Sexual Minority Youth Assistance League (SMYAL), a Washington D.C.-based advocacy group. A receptionist told Fox News that they didn’t receive many calls, despite their number being listed as the senator’s home number.

 “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. 
 
 “That it happened as they were asking questions in a Supreme Court confirmation hearing is just another indication of how broken this process has become". 
 
 White House spokesman Raj Shah wrote on Twitter that the leake information was "outrageous". 
 
 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 tracking account has since deleted the tweets because they revealed the personal information. Fox News confirmed the changes were made to the senators’ pages. The Wikipedia appears to have removed the changes. 
 
 Due to the anonymity of the edits, it remains improbable that a person or persons responsible for the stunt could be caught. It remains unclear whether the publication of such information was done to intimidate the senators following the dramatic hearings on Thursday. 
 
 Graham stood out during the hearings, giving perhaps one of the most impassioned speeches in defense of Kavanaugh, accusing the Democrats of trying to destroy the Supreme Court nominee with the “the most unethical sham since I've been in politics.” 
 
 “What you want to do is destroy this guy’s life, hold this seat open, and hope you win in 2020,” Graham told Senate Judiciary Democrats. “Boy, y’all want power and I hope you don’t get it.” 
 
 Other senators also defended Kavanaugh, including Hatch, who said: “What we have are uncorroborated, unsubstantiated claims from his teenage years” and that Kavanaugh has been treated unfairly.
– 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. Cosko, a George Washington University graduate who also worked for Democratic Sen. Barbara Boxer, had most recently been working as an intern for Democratic Rep. 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.
