Hundreds of protesters gathered at airports in Dallas, Chicago, New York and elsewhere while inside, anxious family members waited and worried for travelers.
At Chicago O’Hare International Airport, brothers Bardia and Ayden Noohi waited for four hours for their father Kasra Noohi -who has an Iranian passport and a U.S. green card – to be allowed through.
They knew Mr. Trump had pledged tougher rules but did not expect they would affect holders of green cards, which allow foreigners to live and work in the United States.
“I didn’t thing he’d actually do it,” Bardia Noohi (32), said. “A lot of politicians just talk.”
Mr. Trump, who took office just over a week ago, had promised during his campaign what he called “extreme vetting” to do more to protect Americans from terror attacks.
