Yes. You may have discovered the problem. Observant Orthodox Jews and some Conservative Jews follow the laws of kashruth. Milchig and fleschig cannot be eaten at the same time or near the time of each other (dairy and meat).
I have no idea if Nadler is observant. His parents were. I don't know if he stops trying to destroy Trump from sundown Friday through sundown Saturday. /s
My comment in post #49 applies. If he was truly observant he'd attempt to keep ALL the rules. So how does he justify bearing false witness against the President?
