US Capitol Police investigating suspicious vehicle near Library of Congress

Officers from the United States Capitol Police (USCP) responded Thursday morning to reports of a suspicious vehicle near the Library of Congress in Washington, D.C.

The USCP called it an "active bomb threat investigation." Aaron Fritschner, communications director for Rep. Don Beyer (D-Va), shared on Twitter screenshots of message alerts he had received from the police agency. One message sent at 9:53 a.m. states, "Madison: Internal Security Threat: move inside office/lock doors, seek cover, and remain silent." A subsequent message states: "Jefferson: EVACUATE. Proceed to your designated assembly area. DO NOT exit out of the west side (First Street) of the building."
