If this FBI investigation doesn't find anything to corroborate Christine Blasey Ford, should Brett Kavanaugh take legal action against her?

I would. If these allegations are unsubstantiated, then that's slander.

100% yes

Personally, I think because of his outburst I think he is a plant to take away women's rights.

No. He is should take his seat with class. His family is the only thing he would give up. He is going to be one of the best ever

I think she should go to the Sheriff's office in whatever county in Maryland and press charges against him. He needs to be back in court.

It's not slander if you know or believe the allegation is true, unsubstantiated or not.

All the ******* way

They won't find whether it happened or didn't happen
