Matt Damon Runs a Hilarious Attack Ad on Jimmy Kimmel's Vice Presidential Campaign -- Watch!


The famous feud is getting political!

This election year is really heating up.

Earlier this year, Jimmy Kimmel launched a faux-vice presidential campaign on his late night show, Jimmy Kimmel Live!, and this week, the comedian's mortal enemy, Matt Damon, released a hard hitting attack ad aimed at taking him down.

In the video, Damon goes after the late night host's long-running bit of "running out of time" for him, questioning his honesty.

But like a true politician, Kimmel, 48, gets out ahead of the ad by going on the offensive -- making fun of the 45-year-old actor's recent man-bun.
