The top official for the U.S. Postal Service said Tuesday he is considering stopping all mail delivery on Saturdays to cut costs.

Postmaster General John Potter's proposal also recommends closing some post office locations and teaming up with private retail outlets.

Last year the USPS lost $7 billion to growing expenses and less consumer usage. Estimates show it will loose $238 billion over the next decade.

"The projections going forward are not bright. We are not going to be able to freeze our labor rates," Potter explained. "We're not going to be able to freeze our costs for fuel and facilities and vehicles. We're hoping that the American public will embrace these changes."

The downturn in business is being blamed on more individuals paying bills online, as well as competition from private companies like Federal Express and United Parcel Service.

Potter added that without his proposed changes, the federal mail service will not survive. Congress will have to approve the changes.
