One thing to consider is that if Comey, as the FBI Director, had evidence that Trump broke the law, why did he hold on to the information and not report it to the relevant congressional committees that oversee it? By holding on to it, Comey abetted a crime (if it was a crime). FBI Directors are not permitted to hold a few cards in their back pockets for future use.
F1,
That's a good point you raise. To whom would Comey have reported it if it's a crime though? Technically, wouldn't it be reported to the Trump appointed Attorney General? Is there a time limit on when he would have to report it?
Also, if it's not a crime...wouldn't it just be a note to be included in the final report once investigation(s) is complete?
I think Trump tried to beat him to the punch by tweeting last week that "Comey better hope our conversations weren't recorded before he starts leaking stuff".
