Hah I read that late in the election Bubba and Hillary had a yelling match about how she should be handling her campaign, and that at one point he threw his phone off the balcony, on one of those sketchy sites.
I'm sure emotions run pretty high when the stakes are so high so it wouldn't surprise me at all and I wouldn't blame them for some yelling.
AP had the registry story too:

Mentions that there used to be such a thing after 9/11, and I read another article that said such a system for incoming Muslims would probably be constitutional.
