The law is clear: Trump can’t use the military to police America’s streets

“As Chicago braces for an influx of federal troops, it is critical to focus on last week’s ruling by a federal district court stating that President Trump’s June deployment of the National Guard to Los Angeles violated federal law. As national security experts who filed an amicus brief to support California’s challenge, we strongly support the holding of this case that the president has no authority to use federal troops to police America’s cities. This flagrant continued assault on U.S. cities and citizens is illegal, un-American and just plain wrong. In a careful but ultimately devastasting rebuke of the administration, Judge Charles Breyer held in Newsom v. Trump that the government’s use of federal troops violated an 1878 statute called the Posse Comitatus Act, which forbids the government from using federal troops for law enforcement purposes.” (09/10/25)
