The U.S. Postal Service is pushing for Saturday mail delivery to stop by Memorial Day in order to save billions of dollars a year.
Congress first has to approve the legislation. Postal Service officials said going to five delivery days a week would save the Postal Service $2.7 billion a year.
Legislation to end Saturday paper mail, combined with changes to how the agency makes pension payments, would make the Postal Service profitable.
That hasn't happened since 2007.
