The U.S. Postal Service will soon cut off Saturday mail delivery, and will probably go to a three-day-a-week schedule by 2025, Postmaster General Patrick Donahue told the USA TODAY editorial board yesterday.

The United States Postal Service, with sharply reduced usage in the age of Facebook, Twitter and e-mail, has struggled to make ends meet in recent years.

It faces an estimated $8.3 billion deficit this year, and, most pressingly, has a $5.5 billion payment due September 30, to cover its retirees' health benefits.

"On September 30th, I won't be able to pay my bills," Donahue told USA Today.

Senator Tom Carper (D-DE) has introduced legislation that would allow the Postal Service to scrap Saturday delivery, which Donahue estimates would save move than $3 billion every year.
