Conservative commentator Andrew Breitbart is dead at 43

(FoxNews.com) - Widely read conservative Internet publisher Andrew Breitbart, whose flare for battle with politicians and the mainstream media earned him a reputation as one of the nation's most influential commentators, died Thursday.

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."
