What are people saying?

•  “This was an act of terror, and a particularly cowardly act of terror, aimed at innocent civilians, aimed at people going about their lives who had no idea what was about to hit them,” Mayor Bill de Blasio told a news conference.

This was a cowardly act of terror. It was intended to break our spirit. But New Yorkers are resilient. We will be undeterred.

Donald Trump responded to the deadly attack in New York  via Twitter, and said: 

In NYC, looks like another attack by a very sick and deranged person. Law enforcement is following this closely. NOT IN THE U.S.A.!

We must not allow ISIS to return, or enter, our country after defeating them in the Middle East and elsewhere. Enough!
