PIERS MORGAN: Grover Norquist Defiant on Anti-Tax Pledge

Grover Norquist has become more and more agitated as today has progressed, whining about Republicans' "impure thoughts" to Soledad O'Brien this morning and making veiled threats to them on Neil Cavuto's Fox News show.

Unless he's presenting the "Top Ten Reasons Why My Pledge is More Important Than America" on Letterman tonight, Norquist saved the best for last in this "below the belt" interview with Piers Morgan.
