Actor Michael Moriarty, who attacked the Clinton administration for its get-tough campaign against television violence, has quit the series "Law & Order" because NBC tried to shut him up, his publicist said.

Moriarty quit after he was yanked from appearances on two other NBC shows, "Now" and "Today," publicist Gary Springer said."When you get dropped from two shows on your own network within two days of one another, you know something's up," Springer said. "It's obvious to Michael that NBC is trying to censor him and his views."

Moriarty resigned Thursday. "Law & Order" producer Dick Wolf said Friday that the resignation came "as a complete surprise."
