PolitiFact.com

PolitiFact.com is a project operated by the Tampa Bay Times, in which reporters and editors from the Times and affiliated media outlets "fact-check statements by members of Congress, the White House, lobbyists and interest groups". They publish original statements and their evaluations on the PolitiFact.com website, and assign each a "Truth-O-Meter" rating. The ratings range from "True" for completely accurate statements to "Pants on Fire" (from the taunt "Liar, liar, pants on fire") for false and ridiculous claims.
