Is GOP using McCain to set up impeachment?

7. If there were an alterior motive...

I'd have to believe it was an attempt to scotch the investigation by tricking Comey into making some kind of premature claim of guilt or innocence. Comey has been there. He botched the Clinton announcement, and the letter, well.

Not likely Comey would take the bait here. McCain can submit any letters he wants, I doubt Comey will spill anything about on ongoing investigation in open session or in later remarks.
