The Senate confirmed Senator Marco Rubio, Republican of Florida, on Monday as America’s 72nd secretary of state, putting a former political rival of President Trump at the helm of American diplomacy.
Mr. Rubio, 53, was unanimously confirmed in a 99-to-0 vote, becoming the first Latino to occupy the job and Mr. Trump’s first cabinet secretary to be confirmed.
As he replaces Antony J. Blinken in the job, Mr. Rubio confronts a daunting list of foreign policy tests. They include the war in Ukraine, a fragile cease-fire in Gaza and, in what Mr. Rubio calls the century’s defining challenge, China’s global ambitions.
But perhaps his biggest hurdle will be managing his relationship with Mr. Trump, whose temperament and worldview are very different from his own. Over three terms as a senator, Mr. Rubio was known for his hawkish foreign policy views with a heavy emphasis on human rights. Mr. Trump is a skeptic of foreign entanglements and takes a transactional approach to the world.
Foreign diplomats will also closely study the relationship between the president and Mr. Rubio, given that they clashed with memorable bitterness as rivals in the 2016 Republican presidential primaries. Mr. Trump was never in sync with his first secretary of state, Rex W. Tillerson, and fired him over social media after a little more than a year in the role.
Mr. Rubio was born in Miami in 1971 to parents who left Cuba for the United States in 1956, shortly before Fidel Castro took power in the island’s communist revolution. His father worked as a bartender and his mother as a hotel housekeeper, and the family spent several years in Las Vegas before returning to Miami. Mr. Rubio graduated from the University of Florida in 1993 and then earned a law degree from the University of Miami. He served in the Florida House of Representatives, including as its speaker, from 2000 to 2008.
