California on Monday filed a lawsuit against the Trump administration, accusing the US president of “unlawfully” federalizing the state’s national guard to quell immigration protests in Los Angeles.

Trump’s extraordinary deployment of troops to Los Angeles exceeds federal authority and violates the 10th amendment in an “unprecedented usurpation” of state powers, according to the court filing.

“The Governor of the State of California and the State of California bring this action to protect the State against the illegal actions of the President, Secretary of Defense, and Department of Defense to deploy members of the California National Guard, without lawful authority, and in violation of the Constitution,” the complaint states.
