This post is inaccurate in two ways. One, these ads are mandated by law. Even if you are hiring people through normal modern channels like online ads, you must legally show that you placed a newspaper ad because the law is old and expects old-fashioned ads. Obviously they don't want candidates through this pipeline but that hardly means they don't want candidates! Two, this legal requirement is for green cards / permanent residency, for a candidate already hired via H-1B or equivalent - and a green card allows immigrants to move jobs and otherwise demand a genuine market rate just as if they had generations of American blood. I don't think this tweet was intended to be nativist propaganda - replies make it sound like he was just ill-informed - but it's still nativist propaganda.
