A plaque honoring police officers who served during the January 6, 2021 attack on the U.S. Capitol has been installed at the building, three years after federal law required its placement.

Workers installed the commemorative plaque during early morning hours, making it visible to Capitol visitors. The installation comes after a significant delay from when the plaque was mandated by Congress.

The plaque serves as a reminder of the events of January 6, 2021, when a crowd of supporters of then-President Donald Trump breached the Capitol building during the certification of the 2020 presidential election results. Multiple police officers were injured during the incident as they worked to secure the building and protect lawmakers.

Congress passed legislation requiring the installation of the memorial plaque to recognize the service and sacrifices of law enforcement officers who responded to the Capitol breach. The law specified that the plaque should honor those who fought and sustained injuries while defending the Capitol.

Visitors to the Capitol can now view the plaque as a permanent memorial to the officers' service during one of the most significant security breaches in the building's history. The three-year delay in installation had drawn attention from lawmakers and advocacy groups who had pushed for its timely placement.
