While it will not hold up in court, Senator Palmer uses it to ruin Carl publicly while simultaneously speaking the truth about Keith's involvement in the accidental death of Lyle Gibson.

Lynne Kresge is an advisor to President David Palmer, played by Michelle Forbes. Kresge is frequently at odds with Eric Rayburn, who thwarts her efforts to inform the President of a threat at CTU.

John Keeler, played by Geoff Pierson, first appears as a presidential candidate in Season 3, who is approached by Sherry Palmer who offers to help him blackmail David Palmer out of office, thus leaving him with an easy victory in the upcoming election. After a series of scandals Palmer chooses to withdraw from the race and by the start of season 4 Keeler is now President. As the season progresses, terrorists gain control over a stealth fighter and use it to shoot Air Force One out of the air while Keeler and his son are aboard. Keeler himself survives, but is left in critical condition and unable to continue his duties as President. Vice President Charles Logan is sworn into office as President in his place. His subsequent fate is unknown although in season 5, set 18 months later, Logan is still President, so presumably Keeler had either died or been unfit to resume office. Keeler's fate was deliberately left ambiguous because Fox forbade the killing of an incumbent President on screen. It is commonly believed in 24 fandom that Keeler indeed died on the accident but after the end of Day 4, much like Wayne Palmer was killed off after the events of Day 6.
Walt Cummings, played by John Allen Nelson, is Chief of Staff under Charles Logan.

During Day 8, Suvarov returns in the 22nd episode when Former President Charles Logan calls him and tells him that Jack Bauer had killed the Russian Foreign Minister Mikhail Novakovich.

Eleven weeks prior to Season 6, Fayed planned a series of suicide bombings in 10 different American cities that killed over 900 people. He also plans suicide bombings in the early hours of Day 6 on a bus in Los Angeles, a Baltimore mall, and a Chicago hotel, which kill over 200 more people. He contacts President Wayne Palmer and claims that Hamri Al-Assad is the true mastermind (when Assad in fact is trying to make peace with the United States), and that he will reveal Assad's location in exchange for Jack Bauer. Palmer eventually secures Jack's release from the Chinese, and hands a willing Jack over to Fayed. While torturing Jack, Fayed reveals to him that he is the true mastermind. Jack escapes, and leads the investigation against Fayed. He eventually obtains 5 suitcase nukes, and uses one of them to destroy Valencia, killing another 12,000 people. However he cannot arm the remaining 4 nukes, so he captures and tortures Morris O'Brian, until he arms them. However, as CTU closes in, Fayed leaves behind one suitcase nuke to cover his escape, which CTU is able to disarm.
