The Secret Service special agent in charge of President Bartlet’s detail is Ron Butterfield.
Ron Butterfield is a recurring fictional character on The West Wing, played by Michael O’Neill. As head of the presidential protective detail, he is responsible for the security of President Josiah Bartlet and regularly coordinates with the White House staff during threats, travel, and emergencies.
Butterfield is portrayed as controlled, professional, and direct. He often has to deliver unwelcome security information to senior officials, including restrictions on the president’s movements or warnings about potential danger. His job places him close to major plotlines without making him part of the political staff.
The names in the wrong options belong to other characters. Simon Donovan is another Secret Service agent, assigned to protect C. J. Cregg, while Mike Casper is associated with the FBI and White House liaison work. “Gerald” is not the established name of Bartlet’s detail chief. Butterfield remains connected to the president’s protection throughout the series, including its later seasons.
