Marco Antonio Rubio (/ˈruː.bi.oʊ/, ROO-bee-oh; born May 28, 1971) is an American politician, attorney, and diplomat serving as the 72nd United States secretary of state since 2025. A member of the Republican Party, he represented Florida in the U.S. Senate from 2011 to 2025. Rubio is also the acting national security advisor and acting archivist of the United States.
Rubio is a Cuban American from Miami, Florida, and attended law school at the University of Miami. After serving as a city commissioner for West Miami in the 1990s, he was elected in 2000 to represent the 111th district in the Florida House of Representatives. As the Republican majority leader, he was subsequently elected speaker of the Florida House; he served for two years beginning in November 2006. Rubio left the Florida legislature in 2008 due to term limits, and began teaching at Florida International University. In a three-way race, Rubio was elected to the U.S. Senate in 2010. In April 2015, he launched a presidential bid instead of seeking reelection. He suspended his campaign for the presidency on March 15, 2016, after losing to Donald Trump in the Florida Republican primary. He then ran for reelection to the Senate and won a second term. Despite his criticism of Trump during his presidential campaign, Rubio endorsed him before the 2016 general election and was largely supportive of his presidency.
