(AP) - A new spending bill passed by Congress continues the requirement for six-day mail delivery.
But some lawmakers and postal officials say plans to cut Saturday service should proceed.
The postal service last month announced it would switch in August to five-day service for first-class mail but continue six-day package delivery.
Some lawmakers say a long-standing provision in the new spending bill requires six-day delivery.
Postal authorities argue they still will have delivery over six days. The difference is that not all mail will be delivered all six days.
