Donald Trump is ramping up his war against liberal 'sanctuary city' Los Angeles with a new major lawsuit. 

The Justice Department, led by Trump appointee Pam Bondi, sued the city on Monday following weeks of anti-ICE riots and destruction. 

The lawsuit argues that LA's policies attempting to 'deliberately' thwart the work of immigration agents violate federal law.

'Sanctuary policies were the driving cause of the violence, chaos, and attacks on law enforcement that Americans recently witnessed in Los Angeles,' Bondi said in a statement to the Daily Mail.
