President Donald Trump's administration filed suit Monday against Los Angeles, claiming the city is obstructing the enforcement of immigration laws and creating a lawless environment with its sanctuary policies that bar local police from sharing information on people without legal status.

The Trump Administration is suing Los Angeles over sanctuary city policies that limit the city’s cooperation with federal immigration enforcement, claiming that they led to “lawlessness” when thousands of people took to the streets earlier this month to protest the President’s mass-deportation operation.

Mayor Karen Bass fired back at the Department of Justice on Tuesday, calling its lawsuit against her city part of an "all out assault on Los Angeles" by President Trump.Bass said she and other city leaders would not be intimidated by the lawsuit,
