Capitol police in Washington, D.C., investigating U.S. Rep. Patrick Kennedy’s early-morning car wreck have been told by witnesses that the Rhode Island congressman was at a Capitol Hill bar before the crash, the Herald has learned. A source close to the probe said witnesses have told detectives that Kennedy was at the Hawk & Dove before he slammed his Ford Mustang into a security barrier near the U.S. Capitol. The source added that cops are continuing to seek evidence to confirm that Kennedy was at the watering hole.
