Police say they were prevented from giving Kennedy a sobriety test
"The driver exited the vehicle and he was observed to be staggering," Officer Greg Baird, the acting head of the Capitol police union, wrote in a letter to his boss, according to the newspaper Roll Call.
Lou Cannon, president of the Washington chapter of the Fraternal Order of Police, said Kennedy looked intoxicated.
"It's my understanding that he had an odor of alcohol about him and he was unsteady on his feet," Cannon said.
