I heard a couple of scandals (one of them not directly tied to him but too close for comfort) to do with Rubio regarding Congressional or House credit cards may have been why Rubio didn’t get picked.
Rubio is also not eligible and he talks too much. Besides, he’s Cuban and don’t most Cubans already vote Republican?
He just paid it back.
This is chump change. :)
Any politician with a long career is going to have something like that or worse.
