Donald Trump is expected to tap U.S. Senator Marco Rubio to be his secretary of state, sources said on Monday, putting the Florida-born politician on track to be the first Latino to serve as America's top diplomat once the Republican president-elect takes office in January.
Rubio was arguably the most hawkish option on Trump's shortlist for secretary of state, and he has in past years advocated for a muscular foreign policy with respect to America's geopolitical foes, including China, Iran and Cuba.
