But the truth is that what Grassley said doesn't matter, so he really can't have "snuck one in". Ultimately, the only thing that matters for confirmation is what kind of investigation will satisfy Flake and the two women, and they're going to go by what they want, not by what Grassley said in committee.
Again, the key point is whether or not they are satisfied with limiting it to Ford, or whether they'll demand an investigation into Avennati's crap as well.
Flake, at least, VOTED to limit it to Ford’s allegation.
