Topic in the 2004 Vice-presidential debate
FactCheck.org became a focus of political commentary following the 2004 vice-presidential debate between Dick Cheney and John Edwards. Cheney cited the website, claiming that the independent site defended his actions while CEO of Halliburton. Cheney's claim is disputed by FactCheck.org as wrong, saying that "Edwards was mostly right" when talking about "Cheney's responsibility for earlier Halliburton troubles".
Cheney's reference created some controversy because he incorrectly cited the web site's address as "FactCheck.com." At the time of the debate, factcheck.com was controlled by Frank Schilling's company Name Administration Inc., who quickly redirected the address to point to an anti-Bush website owned by Bush critic George Soros.
