I just watched what was on your link and wonder how a senator, Al Franken, can ask a candidate for speculation on something that he himself says was not verified. I also believe he did "st st stammering or twwiit ch ching, or sha shaking".
Perhaps that's your point and you're offering irony, or parody?
I even wonder, in legal sense, is it possible to lie about speculation?
Perhaps that's why Sessions smiled at Franken's speculative question?
Let's hope Franken learns to ask questions with foundation next time, and let's hope he works on his presentation skills for a better performance, one worthy of the position he holds.
The position of AG is very important, and deserves better challenge than Franken offered. There are better choices in Congress for that type of questioning.
