Rep. Patrick Kennedy (D-R.I.), who has had a long-running struggle with substance abuse, is returning to rehab, he said in a statement today. “I have always said that recovery is a life-long process and that I will do whatever it takes to preserve my health,— Kennedy said. “In consultation with my doctor, I have decided to temporarily step away from my normal routine to ensure that I am being as vigilant as possible in my recovery.—Kennedy completed a monthlong treatment program in 2006 after he crashed his car into a Capitol barricade while intoxicated. Under a plea deal, he pleaded guilty to one count of driving under the influence and was sentenced to a year of probation and 50 hours of community service. The Rhode Island Democrat has been open about his battle with addiction, linking it to his push for mental health parity. “I hope that in some small way my decision to be proactive and public in my efforts to remain healthy can help remove the stigma that has served as a barrier for many Americans reluctant to get the help they need,— he said in his statement.
