Conservative blogger, media publisher and activist Andrew Breitbart has died at the age of 43, according to his website.
He died of natural causes early today, the website says in a statement.
His death was confirmed by Joel Pollak, editor-in-chief of his website, who says he was at the hospital, the Associated Press reports.
Breitbart was an outspoken critic of the mainstream media. His efforts were behind controversial investigations that led to the resignations of former Rep. Anthony Weiner and former Agriculture Department official Shirley Sherrod.
He was lionized by his fans for his efforts at exposing government corruption and media bias, the AP says.
Here is the statement posted at breitbart.com:
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.
Andrew recently wrote a new conclusion to his book, Righteous Indignation: "I love my job. I love fighting for what I believe in. I love having fun while doing it. I love reporting stories that the Complex refuses to report. I love fighting back, I love finding allies, and—famously—I enjoy making enemies. Three years ago, I was mostly a behind-the-scenes guy who linked to stuff on a very popular website. I always wondered what it would be like to enter the public realm to fight for what I believe in. I've lost friends, perhaps dozens. But I've gained hundreds, thousands—who knows?—of allies. At the end of the day, I can look at myself in the mirror, and I sleep very well at night."
Andrew is at rest, yet the happy warrior lives on, in each of us.
