Does the First Amendment preclude the US from imposing prohibitive taxes on media? It'd be clearly unconstitutional to ban them outright; so, where and how's that line drawn? late edit: I just want to note the text of POTUS' announcement includes this: "It is, in addition to everything else, messaging and propaganda!" The overtly expressed motive here is animus towards the content of the speech (not some content-neutral factor like trade balances).
