There has been some concern, including from Twitter talk at least that "Trump" directly is involved, of reports of FCC investigation of some Colbert remarks. Feel this is overblown: particularly if they get enough complaints, the FCC is going to investigate. Any fine would be different. As to going too far as matter of discretion, in the heat of the moment, you are going to go that extra bit. Sort of the point of a "rant." Also: PC thoughts.
