— The Port Authority of New York and New Jersey, together with World Trade Center developer Larry Silverstein, is suing seven insurers over delays in payments they say are needed to rebuild on the site of the Sept. 11, 2001 terrorist attacks. According to Silverstein, some insurers have been suggesting they might halt monthly payments following a new deal, called the Conceptual Framework, which shifted responsibilities and financing between himself and the Port Authority. Silverstein has said that without the insurers’ funds, the World Trade Center site cannot be rebuilt.
