Skip Tyler is the quaternary antagonist in White House Down.
He is portrayed by Jimmi Simpson.
Skip Tyler is a computer hacker and the technical specialist in Emil Stenz's group, who is working with Emil, Martin Walker and Eli Raphelson. He used to work for the NSA, but was fired for rewriting launch missile coordinates for Apple Headquarters due to having grown tired of their music-sharing policies. He is hired by Walker and Raphelson to hack into the defense system so that they can use the missiles to blow up numerous cities. He also had a bomb set up in the sewer to prevent John Cale and President Sawyer from escaping, but ironically, he later died setting off said bomb.
