Well, I can't help you much there. You need to understand what I said in order to understand what's going on. But the bottom line is this:
If the article from Breitbart is right about Trump's motivation, and it seems likely that they are given that they're almost a mouthpiece for Trump, then it's a problem for Trump. If he fired Comey in an attempt to shut down the FBI's lawful investigation, then it's probably obstruction of justice. Even if the investigation had no merit and was unreasonable, that doesn't mean you can interfere with it. But the fact that at least one of the investigations has just yielded its first subpoenas the very same day suggests that there is merit to it.
So, to recap, if the obvious is true, and Trump fired Comey to try to stop their investigation into his Russia connections, that is probably a fresh, new crime, committed yesterday by Trump, regardless of the merits of the FBI investigation.
