History Characters / TwentyFourWhiteHouse

->'''Played By:''' John Allen Nelson

* CommanderContrarian /HonestAdvisor: He has shades of both. Taylor appreciates his counsel, but not how publicly and pessimistically he expresses it.

* AdultFear: Her daughter is held hostage by Henderson later on.

* BaldOfAwesome: While he starts a bit shaky, by season 4 and 5 he becomes unambiguosly one of the heroes.
* DeadpanSnarker

* CloudcuckoolandersMinder: Her relationship with Martha initially has shades of this.

* GlamorousSingleMother: She has an eight-year old daughter, whose father doesn't seem to be in the picture.

* TheMole: Ultimately turns out to have been David Palmer's White House source.

* ReverseMole: Ultimately turns out to have been David Palmer's White House source.

%%* BaldOfAwesome: While he starts a bit shaky, by season 4 and 5 he becomes unambiguosly one of the heroes.
%%* DeadpanSnarker

* FakeGuestStar: While his status as a recurring character in Seasons 1 and 4 is justified (he appears sporadically during the former, while in the later he only appears in the last third), in Seasons 2 and 5 he appears prominently throughout and is only absent from a few episodes in each; both times he plays extremely prominent roles in the day's events.

* AlasPoorVillain: Make no mistake: Cummings is a gigantic {{Jerkass}}, incredibly smug, and a traitor to his country, but the way he goes out is so pathetic that one can almost pity him.

* ManipulativeBastard: Subverted. He only ''thinks'' he is.

* HonestAdvisor: To Allison Taylor.

%%* BitchInSheepsClothing

* ManipulativeBitch: Plays both enemies and friends alike as the story goes by.

%%* SmugSnake
* SuspiciouslySimilarSubstitute: Much like how her mother represented being the new BigGood ala David Palmer, Olivia seems remarkably similar to Sherry.

%%* BaldOfAwesome

* KarmaHoudini: Despite his role in inadvertently causing the possible death of Lynne Kresge, he's never charged or imprisoned for it, and goes on to work as an adviser for another presidential administration.

** TheBusCameBack: On Day 4 he returned as Logan's adviser.

* MyGodWhatHaveIDone: [[spoiler: Tries to call off the hit against Hodge after having a little time to think about it, although it's too late]].

* PutOnABus: [[spoiler: To prison, with an unclear sentence, between Day's 7 and 8]].

* OhCrap: Displays this when Palmer is [[spoiler: poisoned by Mandy in the finale]].

* BearerOfBadNews: She's the one to tell Jack that [[spoiler: Logan is behind everything]].

* IWillOnlySlowYouDown: Refuses to have Wayen stay with her [[spoiler: after being shot in the leg]] due to feeling Jack will need backup to get the recording.

* WhatExactlyIsYourJob: Her official title is never mentioned, although based on her responsibilities, Chief of Staff to the First Lady would be a good guess.
* WhatHappenedToTheMouse: It is left unrevealed whether or not [[spoiler: Henderson kills her after forcing her to tel lwhere Jack and Wayne are heading]].

%%* ManipulativeBastard

%%* CoolOldGuy

%%* ManipulativeBitch
%%* MyGodWhatHaveIDone

%%* ChuckCunninghamSyndrome

* WhatHappenedToTheMouse: Last seen in critical condition being wheeled into an ambulance, she never reappears after Season 2. Given how Mike Novick, who inadvertently put her in that situation, continues to serve in a high position of the Keeler and Logan administration's, this would likely mean Lynne either died or survived and refrained from speaking out against him.

* NiceJobFixingItVillain: If Cummings had decided not to orchestrate the assassination attempt on Jack's life and had just let him willingly be taken in by the Chinese at the end of Day 4, then very likely when the events of Day 5 happened Jack would have still been imprisoned in China which would have left him unable to expose its conspiracy.
* SmugSnake: Like the Unwitting Pawn trope states, he believed he was much more of a major player than he actually was, which allowed his eventual downfall to hit him that much more harder before he's betrayed by the very folks he thought were working for him and killed. Which would also mean Cummings would likely still be alive.

->'''Played By:''' Peter [=MacNicol=]

->'''Played By:''' Ross [=McCall=]

* GenreSavvy: During Day 5, when Jack has commandeered a plane in his plan to stop President Logan, Mike is one of the few to openly rebuke the claim that Jack could go rogue, noting how much Jack had done for the country up to that point.
