Although the Postal Service "receives no tax dollars for operating expenses and relies on the sale of postage, products and services to fund its operations," as stated on its website, it is governed by Congress, and had been hoping members would pass legislation to help lessen its financial burdens.
"It's unclear at the moment how the Postal Service has the authority to quit delivering letters on Saturdays. Previously, they've said they need Congress to change current law to do so," reports CNN Money.
Various news reports say the Postal Service needs tens of billions of dollars to be saved. In July 2011, the Postal Service announced the closure of 3,600 post offices across the country in an effort to save money. (Its locations in Bellmore-Merrick were not affected).
