He said he was invited to a sex party
Which he interpreted as being an orgy, so the point is the same. Who goes up to a freshman Republican who is a professed Christian and says "Hey, do you want to go to a sex party"?
Sorry, I'm not buying it. Why not name names if you're not part of the swamp anyway? The way he did it looks like highly transparent virtue signaling. You make something like that up so you can look like you're the only virtuous one in D.C.. I'd be ticked if I was one of the other Republican members, because it implies that all of them either participate, or cover it up.
Guy is a clown even if he is right on most issues. I'd rather have someone right on the issues who isn't a clown.
