US border practices have been awful for a long time, but is this even an actual issue for them, or just a “seems like” kind of question? Seems to me she’s of US origin and wouldn’t be denied entry, but is also a known person of interest so would be interrogated and done whatever with by Homeland Security. The US is an insane country at this point, so what “the U.S.” should do is hard for me to find a clear perspective on how to answer. My ideal US would question her and perform a competent psych evaluation and admit her to care and rehabilitation. (It’d do the same to most of Congress and most megacorproate CEO’s, too…)
