Democratic congressman from South Carolina's 5th Congressional District and House Majority Whip.

The character's name comes from Francis Urquhart, the protagonist of the novel and British version of the TV series of the same name, and Oscar Underwood, the first Democratic House Whip in the United States.

Similar to the protagonist of the British version of the series, Frank often breaks the fourth wall in the series and talks directly to the audience.

The character played by Kevin Spacey is Francis Underwood, the House Majority Whip in the United States Congress.

He is a politician's politician, sophisticated, admirable leader, charismatic and ruthless.

His success comes from the fact that he and his wife Claire (played by Robin Wright) will do whatever it takes to climb to the top of power.
