Hundreds lined up at the BJ's Wholesale Club in Orlando Monday afternoon to have U.S. Sen. Marco Rubio sign copies of his new book "An American Son."

The book, which is published in both English and Spanish, is not entirely political.

However, many Republicans and supporters of Rubio hope the 41-year-old first term senator will be selected as Mitt Romney's running mate in the Presidential elections - something Rubio has downplayed interest in.

Rubio will be signing books at the BJ's near Mall at Millenia for two hours.
