Article III, Section 3 of the Constitution: "Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort."
Cheney is essentially accusing Obama of treason.
Hannity caps it off by asking Cheney if the Obama administration "maybe doesn't believe there's a war on terror," and Cheney agreeing that it doesn't.
History has already recorded that Dick Cheney not only was one of the worst vice presidents in history just in terms of governance, but moreover one of the most vicious character assassins and ethics-deprived manipulators ever to set foot in the White House.
Now he's just adding to that legacy.
