MIAMI, FLA. -- Florida U.S. Senator Marco Rubio has been on many short-lists as a possible running mate for Mitt Romney, should Romney land the GOP presidential nomination.
It turns out they may have more in common than political affiliation. Romney is a Mormon, and it turns out that Rubio used to be.
According to the publishers of Rubio's soon-to-be-released memoir, An American Son, Rubio was baptized into the Mormon faith at the age of 8, when he and his family lived in Las Vegas.
When the family left Mormonism, Rubio was 11 years old.
Rubio later converted to Roman Catholicism.
According to his office, he is still a practicing Roman Catholic, though he also likes the teachings of the Southern Baptist church, noting he also has ties to a Miami church affiliated with the Southern Baptist Convention.
Rubio has listed himself as Catholic and Baptist, by turns, according to the Florida House Clerk's Manual. Since 2005, however, the former speaker of the Florida House has identified himself as Roman Catholic.
The early roots of Rubio's religious life as a Mormon are mentioned for the first time in this memoir, and were largely unknown until the notes from the publisher.
It's not the first time Rubio's past has held a surprise, however.
He had claimed that his parents escaped Cuba after Fidel Castro took over, though it turned out that had left the island country years earlier. Rubio later corrected that.
