Eliot Spitzer is denying that his campaign buried news of an alleged drunken driving accident involving his 31-year-old campaign manager, Ryan Toohey.

“There was no cover-up,” Mr. Spitzer, the Democratic candidate for governor, told reporters after a rally yesterday in Harlem. Mr. Toohey was arrested for driving while intoxicated after his car rolled over several times in an October 22 crash on the Niagara Thruway in the upstate town of Tonawanda. The charges were not made public until the weekend, and Mr. Spitzer said repeatedly yesterday that the campaign did not know about the arrest until Friday night.
