This is where Kavanaugh will start to wish he'd been a little more professional - a little calmer - and a little less combative on the stand yesterday.
In all the heat, tears, blubbering, and anger that he could muster up, he said an awful lot of things ... answered a lot of questions with absolutes - and he probably (without watching the video) can't actually remember a half of what he said to the Judiciary Committee.
What he did yesterday opens up a very wide door now for the FBI to determine that Kavanaugh perjured himself under oath. They only have to find one instance ... just a single confirmed instance of Kavanaugh perjuring himself ... and his goose is cooked.
As an aside, there may already be confirmed witnesses to Kavanaugh perjuring himself yesterday. He claimed (under oath) that he didn't watch Dr. Fords testimony on TV ... and there are multiple people that note they saw him with a group of people in an office watching Fords testimony on TV.
Perjury isn't one of those things that's measured in "degrees" ... you're either honest under oath (and are believable), or you're dishonest under oath (and can't be believed).
And now the FBI is on board, likely with a few hundred agents already being sent out into the field to undertake the investigation.
Kavanaugh will be lucky to be selling pencils outside a Walmart in a year - let alone sit on the highest bench in the land.
