Postal Service delays closings until May 15 – Dec. 13, 2011.

The U.S. Postal Service has agreed to hold off on closing any more post offices or mail facilities until May 15, 2012, to allow Congress time to work on a plan to save the service.

The U.S. Postal Service agreed to voluntarily enact a moratorium on closures, after a series of talks with senators, lawmakers said. Sen. Richard Durbin said the postal service agreed to the deal, and he called it a challenge to Congress to “put up or shut up.”
