Setting: Rayburn House Office Building Thursday afternoon.

Cause: The National Association of Drug Court Professionals, a group trying to steer more addicts into treatment than jail.

Bona Fides: Sheen is a long-time advocate for the cause. Also, his son — self-professed warlock and rock-star-from-Mars, Charlie Sheen — has struggled with addiction issues for years.

What he wants: To preserve federal funding for drug courts.

How he looked: Silver-haired and “West Wing” presidential in a navy blue suit.

Heartfelt, yet grandiose, oratory: “A dream that helps lift up this nation and all its people to a place where the heart is without fear and the head is held high and knowledge is free, where the world has not been broken up into fragments by narrow domestic walls where words come out from the depths of truth and tireless driving stretches its arms towards perfection” — Sheen started waving his eye-glasses through the air — “where the clear stream of reason has not lost its way to dreary desert sands of dead habit.

Surpise: Didn’t mention Charlie. At all. And sorry, not taking questions from the press.
