Washington- Rep. Patrick Kennedy said Friday he was entering treatment for addiction to prescription pain medication, a decision made after a highly publicized car crash near the Capitol that he said he cannot recall.

Kennedy, D-R.I., said he plans to seek treatment at the Mayo Clinic in Rochester, Minn., immediately.

He announced his decision to reporters at a Capitol Hill news conference. He walked in alone, gripped the lectern, cleared his throat and began haltingly.

Kennedy, who has struggled with addiction and depression, said he had checked into the Mayo Clinic over the Christmas holidays and returned to Congress “reinvigorated and healthy.”

“Of course, in every recovery, each day has its ups and downs, but I have been strong, focused and productive since my return,” Kennedy said in a statement obtained by The Associated Press.

The congressman said he became concerned about his condition after the Thursday morning car accident.

“I simply do not remember getting out of bed, being pulled over by the police, or being cited for three driving infractions,” Kennedy said. “That’s not how I want to live my life. And that’s not how I want to represent the people of Rhode Island.”

As he was leaving the room, Kennedy was asked whether he might resign, and he shook his head no. “I need to stay in the fight,” he said.

The congressman’s father, Sen. Edward Kennedy, D-Mass., issued a supportive statement in which he said he’s proud of his son for admitting his problem and taking steps to correct it.

“He has taken full responsibility for events that occurred … and he will continue to cooperate fully with any investigation,” the elder Kennedy said.
