NYC Mayor Bloomberg: 'Stop This Craziness' at Ground Zero

New York Mayor Michael Bloomberg says it is time to move ahead more quickly with building at the World Trade Center site while material and labor costs are low.

The mayor said on his weekly radio show Friday that it is time to "stop this craziness." He laid some of the blame for delays on the Port Authority of New York and New Jersey, which controls the site.

Two skyscrapers, a memorial and transit hub are already under construction at the site of the Sept. 11 attacks. But several planned towers has been stalled because of financing battles between the Port Authority and the developer.

Bloomberg says the agency should build now "or just get out of the way."

There was no immediate response from the Port Authority.
