The USPS will end first-class mail service this summer after 150 years in a cost-saving maneuver. The move to cut Saturdays will be announced today.
The switch from six days a week to five only affects first-class mail; packages, mail-order medicines, priority and express mail will still get delivered.
Sen. Tom Coburn (R-OK) says the move will save the struggling US Postal Service, which lost $16 billion last year alone, about $2 billion a year.
The Postal Service has lost $41 billion over the past six years as more and more Americans turned to private shippers, email, and online banking.
