Will airlines and others sue for damages arising from this ban? I doubt it with airlines, but I would hope (but not necessarily expect) that they would be successful.
About the inclusion of US LPRs in the ban, <deleted by moderator> Time will tell more. As just about anyone with any legal sense at DHS, DOJ and State ought to have known, hitting LPRs with an entry ban would result in a legal storm of problems. <deleted by moderator>.
