Washington, D.C.—The federal budget request for 2013 submitted to Congress by President Obama on Monday included proposals that would aid the financially ailing U.S. Postal Service, including allowing it to end Saturday mail delivery. Among the provisions, the Federal Employees Retirement System would return almost $11 billion in extra contributions to USPS; in addition, the Postal Service would be allowed to postpone future retiree healthcare contributions of about $15 billion while it streamlines its operations. The budget request also supports USPS' call for a postage rate hike above the rate of inflation, a bid earlier rejected by the Postal Regulatory Commission. Last week, USPS reported a net loss of $3.3 billion in its first fiscal quarter ended Dec. 31.
