Suspicious Vehicle Forces Capitol Police HQ Evacuation, Multi-Block Shutdown

U.S. Capitol Police officers evacuated their own headquarters building on the 100 block of D Street NE Friday morning after locating a suspicious vehicle nearby, triggering a multi-block shutdown of streets and checkpoints just steps from Capitol Hill's Senate office buildings.

Police established road closures along D Street NE between First and Second Streets, First Street NE between D Street and Columbus Circle, and Second Street NE between Massachusetts and Constitution Avenues, while shutting down security Checkpoints 8, 9, and 10, according to FOX 5 DC. Employees inside the headquarters building were directed to remain calm, close doors without locking them, take annunciators with them, proceed to designated assembly areas, and check in with their Occupational Emergency Coordinator, the station reported.

A Familiar Drill on D Street

Friday's evacuation is not the first time the headquarters building has been cleared over a vehicle alert. In September 2023, the same block of D Street NE was evacuated after a K-9 unit alerted to a suspicious vehicle and package, prompting temporary street closures until bomb squad technicians cleared the scene, according to DC Patch. The 2023 incident followed the same broad pattern seen Friday: an unverified vehicle near the headquarters triggers an immediate evacuation until specialized units can confirm there is no danger.

The building at 119 D Street NE has long sat at the center of a dense, security-conscious corridor. The agency that occupies it maintains a workforce of more than 2,200 sworn officers and civilian staff and operates on an annual budget exceeding $700 million to protect 535 members of Congress and millions of annual visitors, per the United States Capitol Police.

A Surge in Threats Against the Capitol Complex

Friday's response comes against a backdrop of record-high threat activity directed at Congress. The agency's Threat Assessment Section investigated 14,938 concerning communications, statements, and threats against lawmakers, staff, and the Capitol complex in 2025 — a 58% jump over the 9,474 cases logged in 2024, the agency reported in a January press release. Officials have attributed part of that surge to online messaging and the perceived anonymity it offers.

The agency has also been armed with recent, real-world reminders of vehicle-based threats near the Capitol. In February, officers arrested a suspect wearing a tactical vest and carrying a loaded shotgun on the Capitol's Lower West Terrace after finding his SUV parked in front of the U.S. Botanic Garden with a gas mask and helmet inside, per the same agency's press release. And in August 2021, a suspect parked a pickup truck on the sidewalk near the Library of Congress and Cannon House Office Building and claimed to have a bomb and detonator, forcing evacuations of nearby legislative buildings before the standoff ended peacefully through multi-agency negotiations.

Heightened Vigilance Since 2021 Attack

Security protocols around Capitol Hill's perimeter checkpoints were tightened after an April 2021 vehicle attack at a Capitol barricade killed Officer William “Billy” Evans and injured another officer, according to Reuters. That attack prompted fortified physical barriers and stricter vehicle screening across the complex, a posture that helps explain why an unverified vehicle near headquarters still triggers an immediate, multi-block clearing of the area.

To keep pace with threats extending well beyond Washington, the Capitol Police expanded formal law enforcement coordination agreements with local departments nationwide from about 115 to more than 350 in 2025, the agency announced. Those agreements allow the Capitol Police to reimburse local departments that assist with congressional security in members' home districts — an arrangement Hoodline reported connects to broader concerns over suspicious vehicles parked near political events far from the Capitol.

As of Friday, the exact nature and contents of the vehicle found near headquarters, along with the identity or intent of its driver, had not been disclosed. It also remains unclear whether the investigation will result in any charges or administrative holds.
