NYC Mayor Bill de Blasio Praises Police Response Amid Fears of More Bombings

He spoke to "Good Morning America' today.

"It's premature to say what would happen next," de Blasio said.

The mayor has his hands full in preparation for this week. The city is hosting the annual U.N. General Assembly meeting, which will draw leaders from across the world.

He said Sunday that police presence would be expanded this week because of the investigation into the bombings, as well as the U.N. meeting.

“You will see a very substantial NYPD presence this week," the mayor said. "Bigger than ever.”
