I was hoping Sessions would throw his weight behind Cruz, but he is playing it cool for now and only aligning in the corner of Cruz and Trump. He did admit the other day that he has NOT talked to Trump in over a month. But to be honest I don’t know that Jeff has talked to Cruz in that time period either.

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!
He might not need to talk to Trump since once of his top aids joined the Trump campaign.
