does congress have the power to do no mail on saturdays and why

Answer 1

Yes, Congress has the power to determine the operating schedule of the United States Postal Service, including whether or not mail will be delivered on Saturdays. Congress can pass legislation specifying the Postal Service's operating hours and days of service. However, any decision to discontinue mail delivery on Saturdays would likely be met with scrutiny and debate, as many individuals and businesses rely on Saturday mail delivery for important communication and services.
