Obscenity is not protected speech, so it is still prohibited on cable. Profanity is not prohibited on cable by the FCC. However, we're talking about news coverage, not dramatic presentation. Unless we're characterizing these speeches in a different way. Rap singers use profanity all the time, yet those words are edited by MTV and BET, and they're now edited from the VMAs and other live awards shows. I still hear the occasional "fleeting expletive" on live sports, and the announcers are usually startled by it.
Here are the FCC rules:

I doubt they ever anticipated the president to be cited for such things.
