A suspect in the presidential shooting is caught; staffers anxiously await news on Bartlet and Josh's injuries; flashbacks show how C.J. and Donna joined Bartlet's campaign.

While the W.H. is hosting a gala dinner for Nobel Prize winners, Leo and the president learn of a suicide bomb in an Israeli cafe that took the lives of two American students in Tel Aviv for a soccer match, and the staff attempts to manage the president's first veto, of a House bill eliminating the estate tax, and the threat of an override the same night. Sam and Toby first try to sway a contentious Dem.
