Miami International Airport appeared to be business as usual on the first day of the Trump administration travel restrictions for nationals of Cuba, Venezuela and Haiti - countries that are a large source of travel and migration to South Florida.

New Jersey communities with ties to banned countries express concerns as families are separated and travel restricted.

Trump also tied the new ban to a terrorist attack in Boulder, Colorado, saying it underscored the dangers posed by some visitors who overstay visas. U.S. officials say the man charged in the attack overstayed a tourist visa. He is from Egypt, a country that is not on Trump’s restricted list.
