Federal judge rules Trump's use of National Guard in LA protests violated Posse Comitatus Act.

A federal judge ruled that President Trump's deployment of National Guard troops in Los Angeles during immigration protests violated the Posse Comitatus Act, which prohibits military involvement in domestic law enforcement. The decision did not require troops to withdraw but blocked further military involvement in civilian law enforcement. This ruling is part of a broader debate over the balance between law enforcement and civil liberties.
