PORTLAND, Ore. —
A group of mostly Democratic U.S. senators sent a letter Thursday to the U.S. Postal Service, voicing concern that mail processing changes could affect postmark dates for mail-in ballots during an election year that will determine control of Congress.
Updated agency policy says postmarks might not indicate the first day the Postal Service received the mail, but rather the day it was handled in one of its processing centers. Those centers are increasingly likely to be further away from certain communities because of recent USPS consolidations, which could further delay postmarks, the 16 senators wrote.
