The alliance, which represents a wide swath of yellow taxi drivers in New York City, called for a temporary stoppage of pick-ups and drop-offs at JFK between 6-7 PM on Saturday. The group also posted a photo of a desolate-looking Terminal 4 at the airport to illustrate its boycott. Trump’s executive order, which bans visa holders from the seven countries from entering the country for 90 days, bans refugees from entering the US for 120 days and also establishes an indefinite ban on Syrian refugees, has sparked protests and chaos at JFK airport.
