  The Congressional Budget Office (CBO) is the U.S. legislative branch agency
  that provides nonpartisan analyses of budgetary and economic issues to
  Congress. CBO publishes the Budget and Economic Outlook, projections of
  spending, revenues, deficits, and debt, cost estimates of legislation, and
  analytical reports. CBO data is distributed primarily as Excel and PDF
  files on cbo.gov; CBO does not currently publish a programmatic JSON API,
  but RSS feeds and downloadable structured workbooks make it possible to
  ingest CBO data into automated pipelines.
