A Jewish councilman in New York City has lost his seat on the city’s immigration committee after tweeting, “Palestine does not exist,” which has led Linda Sarsour to declare a new day in the city as “anti-Palestinian, anti-Muslim comments” will not fly.

Mayor Bill de Blasio has chimed in, saying councilman Kalman Yeger should lose his committee seat if he doesn’t apologize.

Here’s Yeger Monday night, not sounding the least bit apologetic:

It’s spreading.
