President-elect Donald Trump confirmed he'll nominate Sen. Marco Rubio to serve as secretary of state in his next administration.

• Rubio, 53, has deep foreign policy experience and has transformed from a Trump opponent to a close ally who was a finalist to serve as Trump's vice president.
• If confirmed by the Senate, Rubio will become the top U.S. diplomat under a president who has vowed to pursue an "America First" agenda amid the Ukraine-Russia and Israel-Hamas wars.
• Rubio is currently the top Republican on the Senate Intelligence Committee and serves on the Senate Foreign Relations Committee. A Cuban American, Rubio would be the first Latino person to serve as secretary of state.
