Protests erupted at international airport terminals nationwide today to oppose the muslim ban. Terminal 4 at JFK was shutdown as well as the international terminal at SFO. Immigration lawyers appeared en mass at the terminals filing suits and writs of habeas corpus for all those detained. Throughout the day, there were reports on Twitter of people being detained or refused admission on to US bound flights by foreign stationed TSA officers.
Just now a federal judge in Brooklyn issued an emergency stay against the executive order allowing those that have already landed in the US with a valid visa to stay. This effects somewhere between 100 and 200 people. Those that are still abroad or pulled of flights before departing to the US are still out of luck.
