I wonder...
democrat: Did Trump collude with the Russians?
Mueller: Yes, but I couldn’t indict a sitting president.
democrat: Did Trump obstruct justice?
Mueller: Yes, but I couldn’t indict a sitting president.
Republican: Did you coordinate with the democrats on what questions to ask and how to answer them?
Mueller: I’m sorry, I can’t answer that because the DOJ told me I can only address what’s in the Report.
If they really cling to that, the whole investigation is a joke (which it is).
Why investigate someone who cannot be indicted?
No chance Mueller would contradict anything he claimed in his report. To do so would render everything he has said before and hereafter meaningless. It would also destroy any legacy he may have and reduce him in stature to a common political hack.
