The Justice Department will investigate state and local officials who stand in the way of President Donald Trump's immigration crackdown: memo.

Washington — President Trump invoked muscular presidential powers to begin a sweeping crackdown on immigration following his inauguration on Monday, tasking the military with border enforcement, moving to designate cartels and gangs as terrorist groups, shutting down asylum and refugee admissions and attempting to terminate birthright citizenship.

A top US Justice Department official installed by Donald Trump warned prosecutors that they must comply with the president’s hard-line immigration agenda and laid the groundwork for a clash with state and city officials who don’t cooperate with the administration’s crackdown.
