U.S. Capitol Police are responding to reports of shots fired at the U.S. Capitol Visitor Center in Washington, D.C. EMS units are reportedly on the way to treat multiple injuries. Capitol workers were told by authorities to shelter in place due to a "potential security threat." House staffers received an email shortly before 3:00 p.m. ET saying that no one can exit or enter any Capitol buildings and if you are outside to seek cover immediately.
