A Democratic congressional intern was arrested Wednesday and accused of posting the personal information of at least one Republican senator during last week's hearing about sexual assault claims against Supreme Court nominee Brett Kavanaugh, authorities said. U.S. Capitol Police said 27-year-old Jackson Cosko was 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 added that the investigation was continuing and more charges could be filed. Senior congressional sources tell Fox News that 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. He also worked or interned with the office of Sen. Dianne Feinstein, D-Calif., the ranking member of the Senate Judiciary Committee, as well as with at least one other unnamed lawmaker. A LinkedIn page with Cosko's name on it describes him as a "Democratic Political Professional & Cybersecurity Graduate Student." Jackson Lee's office told Fox News that Cosko had only worked there for a couple of months, but 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." Hassan’s office has had two substantial personnel issues in recent months. Earlier 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 Cosko's arrest. Personal information of Sens. Lindsey Graham, Mike Lee and Orrin Hatch was posted on their respective Wikipedia pages Thursday as the Senate Judiciary Committee questioned Kavanaugh over allegations that he assaulted Christine Blasey Ford at a high school party in the early 1980s. All three have professed their belief that Kavanaugh is innocent of the claims brought against him by Ford, with Graham telling the federal judge "you've got nothing to apologize for" amid a fiery rant denouncing Democrats' handling of the allegations. 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 senators appeared to be correct, though the phone numbers didn't appear to be 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 tell 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.

Photographer: Zach Gibson/Bloomberg via Getty Images (CNN) — The US Capitol Police announced Wednesday that they had arrested a suspect for allegedly “doxing” – a form of publishing private identifying information online – lawmakers during the Senate Judiciary Committee hearing last week. “Earlier today, the United States Capitol Police (USCP) arrested the Suspect who allegedly posted private, identifying information (doxing) about one or more United States Senators to the internet,” said Eva Malecki, communications director for Capitol Police, in a statement. According to the statement, the Capitol Police arrested 27-year-old Jackson Cosko of Washington on Wednesday. Cosko has been charged with making restricted personal information public, making threats in interstate commerce, unauthorized access of a government computer, identity theft and obstruction of justice/witness tampering, according to the US Attorney’s Office for the District of Columbia. He’s also facing charges of second-degree burglary and unlawful entry for incidents in Washington. Last week, a Twitter bot that tweets out edits to Wikipedia pages allegedly made by devices with Capitol Hill internet connection, called @congressedits, picked up and tweeted out lawmakers’ personal information when it was added to Wikipedia pages. The account is currently suspended. “The investigation will continue and additional charges may be forthcoming,” the statement said. According to a statement from Bill Miller, a spokesman for the US Attorney’s Office for the District of Columbia, Cosko is in police custody and is expected to appear before Magistrate Judge Deborah Robinson on Thursday in the US District Court for DC. CNN is attempting to contact Cosko or his attorney.

Jackson Cosko, 27, appeared in U.S. District Court for the District of Columbia a day after being arrested for "doxxing" GOP senators on Wikipedia. The U.S. Attorney's Office for the District of Columbia announced that Jackson has been charged with five federal offenses, including making public restricted personal information; making threats in interstate commerce; unauthorized access of a government computer; identity theft; and witness tampering. ADVERTISEMENT He is also charged with two D.C. offenses: Second-degree burglary, which carries up to 15 years in prison, and unlawful entry, which carries up to 6 months in prison. Magistrate Judge Deborah Robinson ordered that Cosko be held in detention pending a hearing set for Oct. 9. Capitol Police began an investigation Sept. 27 when the Wikipedia pages of three unidentified senators were edited to include restricted personal information without their permission, according to the affidavit released by prosecutors. On Oct. 1, two more senator's pages were similarly edited, prosecutors said. Cosko was linked to the case when on Oct. 2 a witness saw him allegedly on the computer in the office of a senator who once employed him, leading to an investigation by Capitol Police, according to prosecutors.

A former Democrat congressional intern was arrestednfor "doxing" three Republic senators while Supreme Court nominee Brett Kavanaugh was testifying in front of the Senate A former Democratic congressional intern was arrested on Wednesday for “doxing” — or posting private contact information online — three Republican senators while Supreme Court nominee Brett Kavanaugh was testifying in front of the Senate this past Thursday, the Capitol Police confirmed in a statement. Jackson Cosko, 27, of Washington, D.C., allegedly was involved in posting phone numbers and home addresses for Sen. Lindsey Graham of South Carolina, Sen. Orrin Hatch and Sen. Mike Lee, both of Utah, The Washington Post reported.

Robinson of the District on Thursday afternoon, the District Attorney’s office for D.C. told the outlet. At the time of the alleged doxing, Cosko was on the staff of Texas Democrat Sheila Jackson Lee. RELATED: Comparisons of Kavanaugh Hearings to ‘The Handmaid’s Tale’ Send Internet into Overdrive The Capitol Police, the DA’s office for the District of Columbia and reps from Jackson Lee’s office did not immediately respond to PEOPLE’s request for comment. It wasn’t immediately clear if Cosko had retained an attorney. Lindsey-Graham-2 Lindsey Graham | Credit: Senator Lindsey Graham/Youtube Jackson Lee’s chief of staff Glenn Rushing did, however, tell the Houston Chronicle that Cosko had only been with the office for a month and has since been terminated. According to the Post, “private, identifying information” about the senators was posted on their edited Wikipedia pages on Sept. 27, 2018, while Brett Kavanaugh was testifying in front of the Senate Judiciary Committee regarding the sexual assault accusations made against him by Dr. Christine Blasey Ford. (Dr. Ford also spoke in front of the Senate that day.) After the information was taken down from the website, the changes were then tracked via IP addresses to computers inside the U.S. Capitol. Graham, Hatch and Lee are all members of the Senate Judiciary Committee and therefore have sizable influence over the judge’s confirmation. Republican Sen. Mitch McConnell spoke about the alleged intimidation tactic on Thursday, according to CBS.
