Former Florida House speaker and Florida candidate for U.S. Senate Marco Rubio does not support changes to the 14th Amendment to disallow birthright citizenship, Rubio spokesman Alex Burgos confirmed to The Florida Independent Tuesday.

The position puts Rubio, a rising star in the Republican party, in opposition to top GOP leaders. Senate Minority Leader Mitch McConnell, R-Ky., and Sens. John McCain, R-Ariz., Jon Kyl, R-Ariz., John Cornyn, R-Texas, Jeff Sessions, R-Ala., and House Minority Leader John Boehner, R-Ohio, have all supported holding hearings into the question. Sen. Lindsey Graham, R-S.C., supports a constitutional amendment to the 14th Amendment to disallow birthright citizenship.

All of the other candidates in the Florida Senate race — no-party candidate Gov. Charlie Crist, Rep. Kendrick Meek (D), and Jeff Greene (D) — have all said that they oppose any change to the 14th Amendment.

The 14th Amendment reads,  “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.” The Supreme Court has repeatedly upheld birthright citizenship.
