Promising an update on Monday, Bloomberg says in a statement that he spoke Thursday with New York Gov. David Paterson, Assembly Speaker Sheldon Silver and New Jersey Gov. Jon Corzine, "and--together with Larry Silverstein and the Port Authority--we agreed to extend the conversation through the weekend. Everyone remains committed to finding a solution."

As GlobeSt.com reported in May, points of contention include issues over how to finance the construction of the WTC towers, as well as the overall size and scale of the project. The friction led Silver to call for a summit meeting, which Bloomberg arranged at Grace Mansion three weeks ago. The summit set June 11 as the deadline for the two entities to work out differences. At that time, Bloomberg said in a statement "we cannot allow this to not get done. It is intolerable to leave this hole in the ground."

Sources from SPI and the Port Authority wouldn't reveal details to GlobeSt.com of exactly what happened during the talks. However, in a statement, Larry Silverstein, chairman and CEO of SPI, says that thanks to great leadership, "we have made significant progress over the past three weeks." He adds, "all stakeholders--public and private--must work together to make good on our repeated vow to rebuild the World Trade Center.

A spokesperson from the Port Authority deferred to the mayor's statement, adding that more would be revealed on Monday. A Paterson spokesman told GlobeSt.com that since the conversation was still ongoing, his office could not comment.
