What if it happened to be true that one US politician (whom btw became rich in a very short period of time [1]) illegally got her citizenship by marrying her brother? Should she be denaturalized or is it cool? (not saying she did marry her brother and lied about it: I'm asking hypothetically what should happen if the accusations turned out to be true).
[1] which in a normally functioning society should be suspicious but apparently politicans enriching themselves, no matter if they're republicans or democrats, is cool
