D'Onofrio, a big Kerry supporter, was said to be devastated over President Bush's re-election. "When PAGE SIX [last week] wrote about 'Law & Order' putting up signs forbidding political discussions on set, it was funny," our source said. "Those signs were put up because of [D'Onofrio]."
About a month before the election, D'Onofrio "insisted" on putting up anti-Bush posters and fliers, "and would attack anyone who disagreed with him," the spy added.
In response, "Law & Order" producers posted signs banning political discussions or anything else that would impede work on set, implying that D'Onofrio had held up taping of the show with his political zealotry.
D'Onofrio's co-stars, Kathryn Erbe, Jamey Sheridan and Courtney B. Vance, are said to be fed up with his antics.
"No one — and I do mean no one — talks to him anymore," the insider added.
