The Postal Service will start a round of plant closures next week

It says the closures will help save money and adjust to a lower demand for first-class mail. The agency plans to close 82 mail processing centers this year. The Washington Post reports many senators don't want the Postal Service to move forward with its consolidation plan. They wrote a letter to Postmaster General Patrick Donahoe, asking the agency to complete an analysis of potential impacts. Critics of the plan say it will slow delivery times and harm the Postal Service's brand.
