Carly Fiorina on Wednesday didn't back down from her claim that several generals retired from the Obama administration because of clashes with the president, even though one of those generals didn't serve in the Obama administration. The Republican presidential candidate said in the CNN debate Tuesday night that Generals David Petraeus, Stanley McChrystal, James Mattis, John Keane, and Michael Flynn were "retired early because they told President Obama things that he didn't want to hear."
