fiveo: You are disingenuous (note the proper spelling), not the SA, when you make the false claim that Sessions invoked executive privilege, a power that lies with the President, not the AG. In his opening statement, Sessions made that clear: “I can neither assert executive privilege nor can I disclose today the content of my confidential conversations with the president.” 

The middle ground that Sessions claims, refusing to answer without a claim of executive privilege, has no legal standing but it does have a legal name — contempt of Congress. He should expect a subpoena soon.
