NEWPORT, R.I. (AP) — The 19-year-old son of U.S. Sen. Sheldon Whitehouse has pleaded no contest to a drunken driving charge. Alexander Whitehouse entered the plea Friday morning in Second Division District Court in Newport. Judge Colleen Hastings sentenced him to 30 hours of community service, an educational course on drunken driving and a $250 fine. His license will be suspended for three months. Whitehouse was arrested early Wednesday in Middletown after police were alerted to an erratic driver. Police say a breathalyzer test indicated his blood-alcohol level was .09. The legal limit to drive in Rhode Island is .08. Police also charged a passenger with marijuana possession. Sen. Whitehouse, a Democrat, and his wife Sandra attended their son's court appearance. The senator said afterwards that his son knows what he did was wrong.
