NEW CITY, N.Y. (AP) - The man accused of crashing a powerboat into a barge on New York's Hudson River, killing two friends, is disputing the charge that he was drunk.
    
Jojo John of Nyack is expected to plead not guilty when he is arraigned Wednesday in Rockland County Court.
    
The charges include vehicular manslaughter and operating a vessel under the influence of alcohol or drugs.
    
The victims were a bride-to-be and her fiance's best man. They were thrown from the boat and drowned on July 26 after the boat hit a stationary barge involved in the construction of a new bridge.
    
Prosecutors say the 35-year-old John had nearly twice the legal level of alcohol in his system. His lawyer disputes the test result and says poor lighting on the barge caused the crash.
