RawStory analyzes the six takeaways-in-advance expected from James Comey's testimony tomorrow. Quotations are taken from Comey's statement.
 
1.) Comey had nine separate private conversations with Trump during a span of only four months. Compare and contrast this with two conversations with Obama in eight years and one of them was just to say goodbye, in late 2016, because Obama is a gentleman. The other conversation was in 2015 and was a general conversation on law enforcement policy issues. On the other hand, the nine separate conversations with Trump included a demand for a pledge of fealty and a request for the FBI Director to do something illegal and unethical, namely drop the Flynn investigation.

2.) Trump told Comey repeatedly that he “expected loyalty” — and wouldn’t easily take “no” for an answer. In a dinner on January 17th Trump said that he "needed" and "expected" loyalty. Comey says that he sat mute and there was an awkward silence. My personal opinion is that Trump made the request because his handler, Vladimir Putin, instructed him to get Comey in the Trump-Putin camp for reasons which are obvious. Trump apparently dropped the subject but repeated it at the end of dinner (and didn't get the response he wanted.) It's no wonder Comey shot to the top of Trump's hit list.

3.) Trump specifically told Comey that he had no involvement with Russian prostitutes. "He said he had nothing to do with Russia, had not been involved with hookers in Russia, and had always assumed he was being recorded when in Russia.” "We have nothing to do with Russia," is the familiar refrain of the entire Trump family, being sung most recently by Eric and Donald Jr. Carter Page even came up with a delightful comment the other day, "the meeting was about nothing," in response to an MSNBC host prodding for details about Page’s Russian involvement. Of course, Carter, people have meetings about nothing all the time.

4.) Despite this, Trump asked Comey if he could somehow prove that the “golden shower” incident never happened. Still on the topic of non-existent Russian ties and equally non-existent prostitutes, Trump actually asked the Director of the FBI to prove a negative, i.e., that the alleged golden shower incident never happened.

”He said he was considering ordering me to investigate the alleged incident to prove it didn’t happen,” Comey wrote. “I replied that he should give that careful thought because it might create a narrative that we were investigating him personally, which we weren’t, and because it was very difficult to prove a negative.”

5.) Trump admitted the possibility that “satellite” associates might have done something wrong.  Wow, Trump actually admitted the possibility that Paul Manafort, with his $12Million Russian payment, or Carter Page, who used to live in Moscow and was investigated as early as September on campaign interference, might actually have done something illegal?
”The President went on to say that if there were some ‘satellite’ associates of his who did something wrong, it would be good to find that out, but that he hadn’t done anything wrong and hoped I would find a way to get it out that we weren’t investigating him,” Comey wrote.

6.) In their final conversation before Comey’s firing, Trump implored Comey to publicly state that he was not under investigation. Here's the grand finale. You may recall Trump saying, "I was told three times by the FBI Director that I wasn't under investigation." Trump kept nagging Comey to publicly state that he was not under investigation, which was technically true at the time, but Comey was reluctant to state such a thing in the event that the investigation did in fact expand to include Trump. Comey was being prudent by not making definitive statements about an issue in an ongoing investigation which had yet to be fully resolved.
Naturally, that was not enough for Trump, who complained of "the cloud" he was under. “On the morning of April 11, the President called me and asked what I had done about his request that I ‘get out’ that he is not personally under investigation,” Comey wrote. “I replied that I had passed his request to the Acting Deputy Attorney General, but I had not heard back. He replied that “the cloud” was getting in the way of his ability to do his job.”

So it's Comey's fault Trump can't do his job. If it's not HIlary's or Obama's, well, by default it must be Comey's. The countdown clocks are ticking and Capital Hill will soon be a rockin'. Stay tuned.
