WASHINGTON (AP) — The U.S. Postal Service said Friday it lost $5 billion over the past year, and postal officials again urged Congress to pass legislation to help the beleaguered agency solve its financial woes. In a positive sign, the loss was a fraction of the record $15.9 billion the Postal Service reported losing last year. But it was still the agency's seventh straight annual loss and came despite its first growth in revenue since 2008.
