This is nothing new. His opinion on this has been out there for some time. 

"Last December, Napolitano raised more than a few liberal eyebrows when he told Fox News anchor Shepard Smith that President Trump might have already been indicted in secret by Robert Mueller and that there was already “ample evidence” to do so."

Once you go public with an opinion, it becomes an innate bias to defend it.  He was wrong of course about Mueller having indicting him(possibly) already last year. 

Nobody has been able to state the crimes that the president has committed yet in 2 years of investigating. But we are to believe that more investigating will turn them up.

Because Trump fired some people who wouldn't do what he wanted them to do? This is what has defined Trump for decades. He's fired tons of people that had nothing to do with the investigation for various reasons that seem like poor judgment for reasons that sometimes don't make sense to others. Good luck trying to prove that he was acting any differently than he always has been his entire life in this case. NOT firing any people associated with the investigation would have been the bizarre aberration for him. 

You have to prove criminal intent. Trump imposing his kind of leadership the exact same way that he always has will make that impossible because you can't show a difference between Trump before and Trump during the investigation. 

Amazing how the MSM, that focused every day for 2 years on the collusion that didn't happen..........instead of recognizing one of the most, if not THE most epic failures of the news media in history............ignores it and is working on damage control to save face for their monumental blunder and letting down the American people. 

If they can just get Trump on something now, they can save face.

Geeesh!
