"Rob Lowe is heading back to The West Wing for November sweeps, at least for five episodes. Martin Sheen himself negotiated Rob's return. Sheen was very unhappy when Rob left the show in a dispute over salary and storyline. The dotted line has not been signed, but the pen is hovering."

I liked Sam a bit so yey. I don't think the show has been the same without him.

Whats your sourse for this news. I havnt read anything about this before
