He won't sue, becasue he has NO CASE. I don't think the reporter has been made to look foolish at all. All I have seen is the goons on Imus calling him names like "schmuck", "little bitch", and Imus whining the WSJ deliberately wrote the article to punish him about his speaking out about vaccines.
Imus has lost it.
Lost what?
Look, I wouldn't try to change your mind about Imus. It's adult entertainment.
If you don't believe Imus is doing good charity work - take your money elsewhere.
