DULUTH (AP) - Duluth postal workers and other Minnesota residents are rallying against plans to close Duluth's mail processing center.

About 100 people protested the closure planned for 2015 outside of the federal courthouse in Duluth on Monday. The group included Minnesota lawmakers and some of the 70 postal service employees who could lose their jobs.

The U.S. Postal Service says it could save nearly $750 million annually with the upcoming round of nationwide closures.

Mail from Duluth and nearby cities would be processed in St. Paul, which opponents of the change say could cause a delay. The Postal Service has said the delay would be minimal.
