Secret Service officers are investigating an apparent attempted suicide in U.S. Sen. Mark Kirk's office because of alleged threats against President Barack Obama.
The man, who is now in protective custody, allegedly broke into Kirk's 35th floor office in the Kluczynski Federal Building at around 3 p.m., broke a window with the base of a flagpole and threatened to jump, a source with knowledge of the incident told NBC Chicago.
Kirk's staff alerted Federal Protective Service agents, who quickly detained the man.
The senator was not in the office. In a written statement, Kirk spokesman Lance Trover said Kirk was on naval duty. Trover declined to comment on whether the man made any statements or threats against Kirk.
The man has not yet been publicly identified and was taken to Northwestern Memorial Hospital for a psychiatric evaluation. He's now under the protection of federal agents, officials said.
The Federal Protective Service is a law enforcement agency within the Department of Homeland Security that provides protection to federally-owned and leased buildings, facilities, properties and other assets, the agency said.
The Kluczynski Federal Building is at 230 S. Dearborn St. in downtown Chicago.
