Pennsylvania Sen. Bob Casey was outside the Capitol when the shooting began on the Hill today – he and nearby tourists were ordered to crouch by a car for their safety, he told reporters in Washington.
"We heard three, four, five pops," Casey said, according to the AP.
He later released this statement:
"My office has received countless calls of concern regarding the incident on the Capitol Grounds today. I was walking outside of the Capitol when I heard a popping noise that sounded like gunfire and the Capitol Police quickly directed us to appropriate nearby shelter. Once the Capitol Police gave the ok, I returned to my office. My staff sheltered in place during the incident. I appreciate the concern of Pennsylvanians. I am grateful for the fast action and professionalism of the Capitol Police and my thoughts and prayers are with officer who was injured in the incident."
