Capitol Hill staffers were briefly on lockdown Tuesday afternoon after a report that a person with a gun had descended on the Capitol complex. Politico's Glenn Thrush published a 3:24 p.m. email to all House of Representatives staffers announcing "A lock down has been initiated for all buildings in the Capitol complex due to the investigation of a man with a gun." The situation has since been "stabilized," and the lockdown will be called off.
