Two other figures who have used the phrase are Nobel laureate economist Paul Krugman and journalist Joe Conason. Conason, in an article called "The vast right-wing conspiracy is back," refers the National Republican Trust PAC and Newsmax Media, which are run by former foes of Bill Clinton and who made attacks on then-President Barack Obama. The National Republican Trust PAC sponsored a campaign commercials against Obama in 2008 which FactCheck.org described as "one of the sleaziest false TV ads of the campaign." One of Newsmax Media's owners "was among the most insistent endorsers of the Obama birth certificate myth" and a popularizer of the canard that Bill Clinton's White House counsel Vince Foster did not commit suicide—as determined by five official investigations—but was murdered.
