For those of you claiming he should sue for slander, defamation of character, etc., my understanding is it's almost impossible for famous people to win cases of that type. I seem to remember reading there are different standards and thresholds for people in the public eye.
I know we have at least a couple of lawyers on here. Can one of you comment on this?
Correct. Public Figures have to prove the additional element of "actual malice" for defamation. Basically, that whoever said the false and defamatory statement did it with the intent to hurt the public figure somehow.
