Donald Trump's former primary opponent Sen. Marco Rubio is meeting with the Senate Foreign Relations Committee Wednesday as the president-elect's secretary of state nominee.

Florida Sen. Marco Rubio received a warm welcome from Senate colleagues Wednesday as he sketched out his plans for implementing President-elect Donald Trump’s“America First” vision as secretary of state.

Trump is inaugurated for a second term. Rubio said confronting China would involve building U.S. domestic industrial capacity. "If we stay on the road we're on right now, in less than 10 years, virtually everything that matters to us in life will depend on whether China will allow us to have it or not.

Sen. Marco Rubio, Donald Trump’s pick for secretary of state, is widely expected to win Senate confirmation to the post.

As the country’s top diplomat, Senator Marco Rubio of Florida, who has a special interest in Latin America, would be tasked with navigating Donald Trump’s efforts to expand U.S. influence.

Marco Rubio is no stranger to grilling nominees during confirmation hearings, but on Wednesday, he was the one in the hot seat as President-elect Donald Trump's pick to be the top U.S. diplomat moves forward.
