The Obama administration has put up a new website, Recovery.gov, to help people track how the recovery/stimulus money is spent.
From the site:
Recovery.gov is a website that lets you, the taxpayer, figure out where the money from the American Recovery and Reinvestment Act is going. There are going to be a few different ways to search for information. The money is being distributed by Federal agencies, and soon you’ll be able to see where it’s going — to which states, to which congressional districts, even to which Federal contractors. As soon as we are able to, we’ll display that information visually in maps, charts, and graphics.
