New York City Mayor Michael Bloomberg says trains between New York and New Jersey should not have been halted because President Barack Obama was in town.

Train service to and from the World Trade Center station was shut down for over three hours Thursday because of Obama's visit to the trade center.

Host John Gambling mentioned the shutdown during Bloomberg's weekly radio show on WOR Friday. Gambling said the Secret Service wanted the trains halted. Bloomberg seemed suprised at the shutdown and said, "Well, you don't have to say yes. This is our city."

Bloomberg noted that the MTA didn't stop the subways.

Port Authority spokesman Steve Coleman said that when dealing with the safety of the president and the first lady, the agency follows the recommendations of the Secret Service and its own police department. He said that's "not negotiable" and "just common sense."
