I really love the West Wing and his character. Always been a great actor imo. Didn't realize he was that young, how awful :(.

Bad times

shame he's gone, he was a good actor, although I also did think he was older than that, I thought he was in his mid 60's at least.

I will forever remember him in The Rock

Leo woke up in his bed again
Startled by all his familiar friends
Burnt out stubs, confectionary wrappers, bottles spent and empty
Leo felt a terror in this world

He sighs, It's not so bad
And goes about his day as if nothing's changed

He finds it so hard to explain
The way he can't communicate
The feeling's there, but he can't say
Why it's so hard to relate to you or anyone

Leo quickened his pace toward his car
He broke into a sprint at twenty yards
As he guessed the dogs came ripping into his arm for fun
Leo got away in his blue car

nooooo. my god, what a shame. a fantastic actor

when I first saw the title I thought you were talking about the episode in season six where he has a heart attack at the end. I really thought the character had died at the end of that episode

Ditto, and in The Negotiator.
