The U.S. Postal Service announced Wednesday that it plans to end Saturday mail delivery, in one of the most significant steps taken to date to cut costs at the struggling agency.
Under the proposal, the Postal Service will continue to deliver packages six days a week. The plan, which is aimed at saving about $2 billion, would start to take effect in August.
It's unclear, though, how the service can eliminate Saturday mail delivery without congressional approval.
For the past 30 years, Congress -- which oversees the otherwise independent agency -- has included a provision insisting on Saturday delivery. That provision still stands, leaving some on the Hill bewildered about the announcement Wednesday.
