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.

President Donald Trump's administration has directed federal prosecutors to criminally investigate state and local officials who attempt to resist its immigration enforcement efforts, according to a memo to Justice Department staff seen by Reuters.
