Rick Scott, a key Trump ally, is emerging as a top contender to lead the Senate during Donald Trump's second term. However, Scott’s rise is shadowed by his past involvement in one of the largest medical frauds in U.

Sen. Rick Scott of Florida fell short in his bid to become Senate majority leader, with GOP senators selecting Senate Minority Whip John Thune to assume the role.

He's a wealthy Floridian who has taken aim at fellow Republicans while pushing to consolidate power in Washington, and his name is not Donald Trump.
