Trump learns lessons from first 'Muslim ban' but raises new questions

Trump rose to power vowing a harsh line on non-European immigration to the United States, thrilling crowds during his 2016 campaign by vowing a wall with Mexico and stunning the then political establishment by urging a "complete shutdown" of Muslims entering the country. On entering the White House the first time in 2017, he swiftly banned travel from seven Muslim-majority countries, prompting mass protests at airports as critics derided his "Muslim ban." With his new travel restrictions, Trump is again targeting US adversaries.
