The point is that in previous attacks on Americans, the opposition party did participate in the investigation but didn't then accuse the President of allowing Americans to be killed, whether it was Lebanon, the Cole bombing, or 9/11. But because Hillary is running for president, we have endless Congressional investigations, 11 hours or her testimony, and an ongoing accusation that she allowed Americans to be killed, even though there is no proof and she wasn't the President. And it again is a distraction from the original point that Trump makes statements that appeal to the racist and misogynist leanings of some voters, and that Rex is guilty by association.
