Leo Mcgarry's Complete Timeline: from Chief of Staff to Vice Presidential Running Mate
The transition from Aaron Sorkin to executive producer John Wells in Season 5 pushed Leo McGarry into unfamiliar territory. The cozy camaraderie of the early seasons gave way to colder geopolitical friction. The defining rupture occurred at the end of Season 5 and the start of Season 6 over the Camp David peace accords between Israel and Palestine.
Leo opposed President Bartlet’s plan to insert American peacekeeping troops into the Palestinian territory, arguing that putting American lives on the line in an intractable conflict was reckless. The argument grew so fierce that Bartlet demanded Leo's resignation. Moments later, walking through the woods of Camp David, Leo collapsed from a massive, near-fatal heart attack.
The heart attack marked a fundamental pivot point in the series narrative. Leo survived, but his tenure as White House Chief of Staff was finished. In an emotional transfer of power, Leo handpicked press secretary C.J. Cregg (Allison Janney) to replace him in the Oval Office. Stripped of his grueling 18-hour daily schedule, Leo briefly wandered the periphery of power, serving as a special counselor before finding an unexpected second act.
