Herman Cain Fires Back At HuffPost Over SimCity Story (VIDEO)

LAS VEGAS -- Herman Cain was one of two presidential candidates who faced reporters in the spin room after Tuesday night's CNN debate. Like in the debate, he spent most of his time defending his 999 economic plan -- this time from reporters.

When HuffPost brought up the similarities between his plan and the default tax system set up in SimCity 4 after the debate, Cain fired back: "It's a lie."

That's also what he told a reporter at a campaign stop last week in Tennessee.

But on Tuesday night he went a step further, saying he had never even heard of the video game.
