you're not doing the careful vetting we should be doing and could allow potential terrorists in. that's the question. at this stage, the question before the court is not really whether it's constitutional or legal. those are sort of, if you will, side issues right now. i mean, they'll get to that later. but right now the question is, do we leave this ban in place -- do we leave the stay in place that stops the government from enforcing the travel restrictions? >> nbc's pete williams in our washington bureau. thank you for joining me. now let's go over to bill crystal, he joins me here on set in new york. bill, let's first talk about what we are -- what we were just talking about with pete williams, which is that this ban is something that is getting a lot of negative attention out there. specifically from protesters around the country, but also from some people in donald trump's own party. who are hearing a lot of pushback against it. my question to you is, how much political capital is the trump administration willing to spend to get this thing through?
