WASHINGTON (AP) — Two senators said Wednesday they want Congress to improve voting opportunities for hundreds of thousands of U.S. military personnel stationed abroad by tightening rules on states for getting absentee ballots to them.

Ahead of the Fourth of July holiday, Sens. Chuck Schumer, D-N.Y., and John Cornyn, R-Texas, said they want to eliminate waivers for states that that fail to mail ballots overseas 45 days before an election. States that miss the deadline would be required to mail the ballots express mail, despite the much higher expense.
