Muriel Walker (b. 1953) is the widow of Martin Walker.

She was portrayed by Barbara Williams in White House Down.


Muriel is first seen when Martin Walker, head of the Presidential Security Detail, is seen getting ready for work on the fateful day the White House is taken over by terrorists. He is seen loading his Beretta 92FS pistol and removing his American flag pin and placing it next to a picture of his son, Kevin. He tells Muriel that he will be working late tonight, tells her that he loves her and leaves without another word. Muriel is later brought in by Carol Finnerty to try to talk some sense into her husband over the phone, but she suddenly reveals that she knew about the plot all along. Rather than try to get her husband to stop, she tells him to avenge the death of their son. Muriel is then taken away by the police. 

She presumably spends the rest of her life in a federal prison for her role in the takeover of the White House, as Carol Finnerty promised she would.
