No, just one. IIRC five-year terms, traditionally though not by law no more than three from one major party and the other two from the other. The guy Trump has nominated now is a Pubbie who would support putting some requirements on Section 230. I think the chair was a renaming of a Biden GOP nominee, Ajit Pai, and he might be a bit squishy. I think Trump may have wasted a Dem nomination? This was the guy. An Obama Dem all the way. Maybe a Kushner payoff to Big Tech? Who knows?
Anyway, Simington is the new guy and the evil Pubbies are apparently dragging their feet on him: https://www.rcrwireless.com/20200917/policy/trump-administration-nominates-simington-to-fcc
Kushnew payoff to big tech? Evidence that Kushner is rotten?
