The websites he founded ran a statement Thursday morning announcing that Breitbart, 43, died "unexpectedly from natural causes" in Los Angeles shortly after midnight. His attorney and editor-in-chief of those sites confirmed his death to Fox News.

 

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

Breitbart was a prolific commentator who founded several websites devoted to covering politics, entertainment and everything in between. Earlier in his career, he worked for the Drudge Report before breaking off to start his own outlets -- including Big Government, Big Hollywood and Breitbart.tv.
