I've seen this a lot, but I don't think it means all that much. The question is, does he refuse to talk about Trump? Or does he refuse to talk about socializing with under 18 year olds?
Now, if the questioning had been
"Have you ever socialized with Trump?"
"yes"
"Have you ever socialized with under 18 year olds?"
"yes"
"Have you ever socialized with Trump and 18 year olds?"
"Taking the 5th"
that would have been more meaningful. But it's likely he was just avoiding admitting hanging out with pre-18 girls.
But this discussion of Epstein completely misses the ball. Everyone knows (now) that Epstein is slime, and it certainly taints everyone he has been involved with, including Trump and Bill Clinton. That's not the issue. The issue is, the prosecutors broke the law in giving him a soft deal in the way they did, and protecting him. And that is not merely an opinion, that is a judicial ruling. And that prosecutor who did that is now the Secretary of Labor. So we have a Secretary of Labor who has been found guilty of protecting a child predator.
Of course, this issue was raised by Diane Feinstein at his approval hearing, and was dismissed by those who supported him. Her concerns are now vindicated. Unless, of course, you think it's not big deal that a child predator protector is Secretary of Labor, because, hey, he's done a great job so far!
Only the best people...
