The American Express card had been a major perk for Rubio as he rose in prominence in Florida politics. It was granted to him by the state Republican Party to pay for recruiting candidates, raising campaign donations and other expenses related to his political work.
Things quickly got messy, the records show.
After his first month with the card, Rubio was notified that he had not paid the bill on time. On top of the Feb. 16, 2005, statement, there was an admonition from American Express in bold letters: “Your account is 30 days past due.”
The warning was repeated again on top of the March bill, this time with a delinquency charge of $39.78 added.
