Florida Senator Marco Rubio's life story might not be true, but it still landed him a book deal. Sentinel, a division of the Penguin Group, has purchased the rights to Senator Rubio's as-yet-untitled tale of his family's journey from Cuba to the United States. Back in October, Senator Rubio's migration saga was the subject of a Washington Post investigation that identified inconsistencies in his personal narrative.

According to Politico, Penguin purchased Senator Rubio's memoir after winning a weeklong bidding war against five other publishing houses. In a statement announcing the deal this morning, Sentinel President and Publisher Adrian Zackheim expressed high hopes for Senator Rubio's book.

"Marco Rubio is one of the brightest rising stars of the Republican Party and will likely be on the national stage for many years to come,” Mr. Zackheim said. “Of equal interest is the emotional story of his family’s journey to the U.S. from Cuba, their exile experience and how that shaped the Senator’s life. ... This will be a very personal memoir that proves that the American dream is still alive and well for those who work to pursue it.”

Prior to the Washington Post's investigation, Senator Rubio, who was elected in 2010, peppered speeches and campaign literature with the tale of his family fleeing Cuba to escape Fidel Castro's Communist revolution. Documents uncovered by the Post showed the Rubios left their home country years before Mr. Castro took power. In response to the Post investigation, Senator Rubio modified his story to say his family originally planned to return to Cuba, but changed their minds once it became "clear that Cuba was headed full speed toward Communism."

Since his election last year, Senator Rubio has been widely touted as a potential VP pick or future presidential nominee. Sentinel hopes to publish his memoirs next fall pending approval by the Senate Ethics Committee.
