Two Senate Democrats late Thursday announced plans to introduce a bill, reports Gizmodo.
They say it would halt any “abrupt operational changes” at the U.S. Postal Service.
Concerns are rising that the Trump administration is attempting to interfere with the flow of mail-in ballots.
The Delivering for America Act is co-sponsored by Sen. Gary Peters (D-MI) and Sen. Tom Carper (D-DE).
Peters is a ranking member of the Homeland Security and Governmental Affairs Committee.
The bill reportedly prohibits any changes to Postal Service standards that will impact the service.
It also protects the speed of deliveries, closures or consolidation, and any reduction in facility hours.
