The more information that comes out, the less political cover Sessions has to keep his job. The more the Deep State is exposed, the weaker Sessions position...as he becomes clearly an obstruction to the people learning about corruption in their government.
The Deep State is Sessions friend - whether he ever intended that or not - and as it weakens, his political cover also weakens. It may not be long until Trump will feel very comfortable having him into the Oval Office for a very serious conversation.
Make Sessions Ambassador to Mexico, but station him in New Mexico.
