In 1999, after the death of 60 Air Force personnel, President Bartlet would strongly send orders to Secretary Berryhill, something that alarmed White House Chief of Staff Leo McGarry. During the crisis, Bartlet became increasingly concerned that Berryhill was intentionally delaying his orders.
After the Josiah Bartlet assassination attempt, Berryhill was listed by C.J. Cregg as one of the officials in charge, along with Vice President Hoynes, Dr. McNally, Secretary Hutchinson, one of the Joint Chiefs of Staff, and Leo McGarry.
It was later stated that Berryhill was unsure of the chain of command following the attempt.
In preparation for a presidential address to the United Nations General Assembly, White House Communications Director Toby Ziegler consulted Secretary Berryhill on harsh language related to Islamic fundamentalists. He was given approval, even though Congressional leaders disagreed with it.
After his customary resignation from the Cabinet at the end of Bartlet's first term, Berryhill was the first hired back.
During the bombings of Qumar by Acting President Walken, Berryhill and Leo McGarry met with Qumari Ambassador Umar Usef. He also expressed his dismay over the bombings. He later joined the Acting President in the Situation Room where he expressed his interest in rounding up support at the United Nations for further action in Qumar.
After addressing the UN, approval of Berryhill spiked, and the Bartlet administration decided to vet him for the spot of Vice President, vacated by the resigned Hoynes. Senate Majority Leader Robert Royce believed there would be no problem in confirming Berryhill, but Speaker Jeff Haffley said he would be unconfirmable. Although very eager for the job, Berryhill was soon dropped as a nominee.
In 2003, Berryhill briefed the President about an upcoming meeting with Germany Chancellor Weisman.When President Bartlet was spending too much time consoling disaster survivors in Oklahoma, Berryhill was among those urging the President to return to Washington and continue his work, including the meeting with Chancellor Weisman.  He was replaced by Arnold Vinick after the 2006 election.
In Arctic Radar and Twenty-Five, Berryhill was portrayed by unknown actors. He was present in the Cabinet in Arctic Radar, although none of the actors were specified as Berryhill. In 25, he was shown in silhoutte.
