Elizabeth "Eliza" Montgomery is a guest character in K.C. Undercover. She is the President's daughter and a college student.
She is portrayed by Mckaley Miller.
K.C. is assigned to Eliza as her bodyguard and secret service agent. However, K.C. begins to grow closer to Eliza and sees that she is more than just a party girl.
Eliza is very social and outgoing, earning the title "The West Wing Wild Child." She doesn't do very well in school and acts out instead in an attempt to be noticed by her father.
She has been kicked out of three different colleges and regularly ditches any secret service agents that are assigned to her.
Eliza has brown hair with blonde highlights, brown eyes and fair skin. She wears either skirts or dresses throughout the episode, "First Friend".
The President of the United States (Her father)
Eliza rarely spends time with her father due to his job, which leads her to be more rebellious in an attempt to be noticed by him. After the kidnap attempt, she reportedly talks with her father and decides to focus more on her studies.
K.C. goes undercover to protect Eliza as her secret service agent. They grow closer until Eliza finds out that K.C. is really working as her secret service agent, believing that their relationship is entirely a lie. They make up after K.C. saves Eliza from a pair of kidnappers.
Marisa, who Eliza knows as Clarissa, befriends Eliza over their love for partying.
- The crossover episode, All Howls Eve makes Eliza's existence a paradox, in that the current president of most shows on the Disney Channel at the time of that episode is confirmed to be Barack Obama (as evidenced by the appearance of Barack Obama impersonator Reggie Brown on "I Didn't Do It" and "Austin and Ally", and Michelle Obama's appearance on "Jessie"), who has no college aged daughter named "Eliza".
