Story highlights The Trump administration has made sanctuary cities a central focus of its agenda

The governments join Chicago in suing over the policy

Washington (CNN) The city of San Francisco and the state of California are suing the Trump administration over its continued pressure on sanctuary cities, adding to a growing number of court challenges to President Donald Trump's immigration agenda.

The city filed its lawsuit over the weekend challenging conditions the Department of Justice recently put on key law enforcement grants to pressure sanctuary cities, and California announced it would be filing its own suit on Monday.

San Francisco's lawsuit alleges that the recent additional requirements on the Edward Byrne Memorial Justice Assistance Grants are unconstitutional.
