I feel confident Cruz has said he's not about to press his few colleagues in the Senate, to cut themselves off from any communication in the White House! They already have that now, they don't need it with another administration!
If Cruz loses the nomination, he still goes forth in the Senate and would look forward to having a very small group of friends. His future is set either way and he's young enough to run again!
Sen. Sessions doesn’t need an enemy in the White House in the full throated Trump vein!

On this we’ll disagree. I think Sen. Sessions would disagree with you as well.
