Washington, D.C. ? Former Mayor Marion Barry was acquitted Wednesday of drunken driving and other offenses stemming from his arrest last year near the White House.

Barry, now a District of Columbia Council member, had been charged with driving under the influence, operating a vehicle while impaired, driving an unregistered vehicle and misuse of temporary tags.

Secret Service agents stopped Barry’s car early Sept. 10, 2006, and said he stopped at a green light and drove through a red one. The agents testified that Barry smelled of alcohol, was stumbling and had red eyes and slurred speech.

D.C. Superior Court Judge Richard Ringell ruled that he could not find beyond a reasonable doubt that Barry was intoxicated. He noted that a breath test later in the evening registered a blood-alcohol content of .02 percent, well below the legal limit of .08 percent.

Barry signed autographs and shook hands with supporters as he left the courthouse.

The 71-year-old council member served six months in prison after he was videotaped smoking crack in a 1990 FBI sting during his third term as mayor.
