The Constitution gives the president of the United States an extraordinarily wide grant of authority to use the power of the pardon. I’m not saying he should. I’m not saying he will. It also allows a president in a national security moment to say to somebody, go do X even if it’s technically against the law and here’s your pardon because I am ordering you as commander-in-chief to go do this.
I’m sure I have no idea what characterizing actions as “technically against the law” adds to the conversation, but the implication is clearly that Gingich thinks the Constitution intended there could be no repercussions for illegal behaviour by any given adminstration.
I think I’ll have to go back and reread James Madison’s notes on the 1787 Constitutional Convention, though I have doubts I will find what Gingrich thinks is there.
