Jay Leno was called on the carpet by the Writers Guild of America West Wednesday as he union looked into claims that Leno violated strike rules last year by writing his nightly monologue, Daily Variety reported today (Thursday). He faces possible expulsion from the union and a fine if the WGA panel concludes that a violation occurred. Leno reportedly was accompanied by his attorney to the disciplinary proceeding. Neither he nor the union would comment on the probe. Leno has claimed that at a meeting with WGA West President Patric Verrone and his Tonight show writers, he said that he planned to write his nightly monologue and that Verrone said, "We're going to look the other way." The New York Times later quoted a Tonight show writer as corroborating Leno's remarks. Verrone, however, has emphatically denied giving Leno a go-ahead.
