As for Carr - he is staunchly in support of first amendment rights. Politico wrote about this yesterday since he split from the rest of the GOP on broader censorship (https://www.politico.com/news/2025/09/16/fcc-brendan-carr-so...). He also can’t take unilateral action - the commissioners would have to vote. But the FCC has a lot of content rules for the mediums they regulate, which have thus far held up in courts (although I find it questionable). In that sense, what he was suggesting may be legal (unfortunately).
