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.
