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.

President Donald Trump began his term by taking a series of sweeping immigration executive actions Monday that included declaring a national emergency at the US southern border, immediately ending use of a border app called CBP One that had allowed migrants to legally enter the United States,

Trump promises to sign executive actions to address immigration and border security. Some will likely spark legal battles.
