Rep. Patrick Kennedy (D-R.I.), who famously crashed his car near the U.S. Capitol three years ago while under the influence of prescription drugs, has checked into a rehabilitation facility, the Associated Press is reporting. “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 said in a statement today. His office isn’t giving out any more information about exactly what he’s being treated for, but the congressman has previously sought treatment for bipolar disorder, alcohol and prescription drug abuse.
