Stunned. Prayers for his wife and children.

Via Big Government:

With a terrible feeling of pain and loss we announce the passing of Andrew Breitbart.

Andrew passed away unexpectedly from natural causes shortly after midnight this morning in Los Angeles.

We have lost a husband, a father, a son, a brother, a dear friend, a patriot and a happy warrior.

Andrew lived boldly, so that we more timid souls would dare to live freely and fully, and fight for the fragile liberty he showed us how to love.

Update: Liberal scum celebrate on Twitter upon hearing the tragic news. (HT: Charlie Spiering)

Update II: Sick.

Update III: Per NBC News:

. . . Breitbart was walking near his home in Brentwood, Calif just after midnight Thursday when he collapsed according to his father-in-law Orson Bean. Someone saw Breitbart fall and called 911. Emergency crews tried to revive him and rushed him to the emergency room at UCLA Medical Center, Bean said.

He is survived by his wife Susannah Bean Breitbart, 41, and four children.

Update IIII: Here’s Slate columnist Matthew Yglesias cheering Breitbart’s death.

Via Washington Free Beacon:

Economics and philosophy expert Matthew Yglesias reacted with glee Thursday morning at the news that conservative journalist Andrew Breitbart had died.

“Conventions around dead people are ridiculous,” the Slate correspondent wrote on Twitter this morning. “The world outlook is slightly improved with @AndrewBrietbart [sic] dead.”

“If you think @AndrewBrietbart’s [sic] opponents shouldn’t be glad he’s dead, you’re not taking his life’s work seriously,” Yglesias added.
