In response to a request by the Senate Committee on Appropriations, CBO offers this analysis. It includes a new economic forecast, updated budget projections, and the agency’s work to date in analyzing the President’s budgetary proposals for fiscal year 2010, as described in brief in the Office of Management and Budget’s A New Era of Responsibility: Renewing America's Promise, released in February 2009. Once the Administration has released the details of those proposals, CBO will complete its analysis.
