Sen. Marco Rubio (R-Fla.) is a college professor on the side. Seriously, he teaches political science classes at the University of Miami on Mondays and Fridays.
The Tampa Bay Times has a piece following the whole Rubio-classroom experience. He's apparently well-liked by students and faculty at the school.
Of course he is. Especially with anecdotes to share like this one:
"I was an undergrad at the University of Florida and I used to ride my bike to school and one day there were five guys jogging in place at a red light. I looked over and did a double take and it was Bill Clinton. He used to jog and stop at McDonald's and get an Egg McMuffin."
(Exercise and McDonald's?)
Here's a video of Rubio in scholarly action:
