This one probably requires a bit of a memory refresher. Last July, Ted Cruz took to the Senate floor and revealed publicly the sort of thing that traditionally U.S. senators keep to themselves: In a private meeting, Majority Leader Mitch McConnell had looked Cruz in the face and lied to him about whether a sneaky back-room deal had been cut to re-authorize the Export-Import Bank. McConnell had insisted three times to Cruz's face, "There is no deal, there is no deal, there is no deal."
That was a lie. Hardly an earth-shaking development. McConnell lies all the time. But usually when McConnell lies, he's protected by the so-called decorum of the Senate that demands no one call him out on it. When you hear stories about Cruz's colleagues hating him, you have to remember that it's not because he's a bad guy, but rather because he doesn't adhere to these self-serving rules. When someone lies, he lets you know it happened.
