The District of Columbia is set to argue in federal appeals court about the National Guard's deployment in the city. Wednesday's hearing follows a court pause on a ruling that deemed the deployment illegal. President Donald Trump deployed the guard in August 2025 for crime-fighting, but city officials argue it's unnecessary and militarizes the city. The case questions the Republican president's authority to deploy the guard in heavily Democratic Washington, D.C., which has limited autonomy. A previous ruling suggested Trump might have unique power to mobilize the guard. The appeals court has allowed the guard to remain while the case is pending.
