Media Matters VP: Breitbart had "passion and commitment"

Ari Rabin-Havt, vice president of Media Matters for America, posted this on the liberal nonprofit's website today:

Media Matters has a long history with Andrew Breitbart. We've disagreed more than we've found common ground, but there was never any question of Andrew's passion for and commitment to what he believed.

Our thoughts and prayers are with his family today.
