Outrage and protests over President Trump’s executive order banning Syrian refugees and citizens of seven predominantly Muslim countries from entering the U.S. began to snowball Saturday as federal officials began implementing the controversial immigration policy enacted Friday.

Reports of travelers — even those with visas and green cards — being detained at airports sparked a growing crowd of protestors to gather Saturday afternoon at New York’s John F. Kennedy Airport. On the other side of the country, there was an online effort to bring demonstrators to the federal immigration office in downtown Los Angeles.
