Sen. Marco Rubio sat down for a wide-ranging, and at times contentious, interview with Univision’s Jorge Ramos, his first since being elected senator in 2010.

The interview, designed to promote his newly-released autobiography An American Son, tackled a litany of controversial topics, such as the Florida Republican’s position on immigration reform and a rift between Univision network and him stemming from a story about a family member that aired in July 2011.

During his successful campaign two years ago, the Cuban-American senator became a wildly-popular figure among conservatives. As the GOP’s fastest-rising Latino star, many in the party view him as a bridge to the Latino community due to his charisma and the fact he’s fluent in Spanish. He has attracted significant vice presidential buzz during this election and speculation has run rampant that he could vie to become the first Latino president in 2016.

But Rubio’s overtures to a national audience of Latinos have been bumpy. His position on immigration is tougher than that of most Latinos and he engaged in a spat with Univision, the most-watched Spanish-language network in the U.S., over the July 2011 story about his brother-in-law, Orlando Cicilia, who was convicted in a drug trafficking case in the 1980s.
