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,

Those policy changes were expected to start rolling in fast in the first hours and days of his second term after a campaign in which Trump vowed to launch the largest deportation operation in the country’s history.

The orders include declaring a national emergency to deploy military personnel to the border, suspending refugee resettlement and ending birthright citizenship.
