The Congressional Budget Office has doubled the estimated increases of some costs resulting from the sweeping health care reform legislation passed this year. A CBO report sent Tuesday to Rep. Jerry Lewis of California, the ranking Republican on the House Appropriations Committee, said the estimated rise in discretionary spending - which is spending requiring annual congressional authorization - over the first 10 years under the new legislation could exceed $115 billion. On March 11, exactly two months earlier, the non-partisan CBO reported the estimated increase for discretionary spending could exceed $55 billion.
