Civil liberties groups and many counterterror experts condemned the measures, declaring it inhumane to lump the victims of conflict in with the extremists who threaten them.
“‘Extreme vetting’ is just a euphemism for discriminating against Muslims,” said Anthony Romero, executive director of the American Civil Liberties Union.
Romero argued that, by choosing countries with Muslim majorities for tougher treatment, Trump’s order breaches the US Constitution’s ban on religious discrimination.
Ahmed Rehab, director of the Chicago chapter of the Council on American-Islamic Relations, said his group would mount legal challenges to fight the order “tooth and nail.”
“It is targeting people based on their faith and national origin, and not on their character or their criminality,” he said.
