Per Wiki, it looks like he was pretty much always a writer (a war correspondent during WWII), other than his work on 60 Minutes.
Sometimes he said things like:
(T)oo much alcohol, too much food, drugs, homosexual unions, cigarettes [are] all known to lead to premature death.
And also that that it was "silly" for Native Americans to complain about team names like the Redskins and that
The real problem is, we took the country away from the Indians, they want it back and we're not going to give it to them. We feel guilty and we'll do what we can for them within reason, but they can't have their country back.
Also, he seems not to have been too impressed by Kurt Cobain.
