LiberGovA free Google custom search engine that indexes freely available, public domain US Congressional websites and other sites of interest.
Sites indexed include Congressional member & committee pages, members' social media (Twitter and YouTube, Google does not have access to Facebook), Federal Congressional databases like FDsys.gov, legislation sites, news, and watchdog/Non-governmental sites of interest. Please note that, while there are a few executive agency sites included which impact on the legislative process (OMB, GAO, executive agencies' Inspector General sites etc), this search is meant to track the federal legislative process centered around Congress.
