(CNN) — Andrew Breitbart, the conservative blogger whose posting of a sexually explicit photo of U.S. Rep. Anthony Weiner led to the congressman’s downfall, has died, his attorney confirmed Thursday.

He was 43.

Joel Pollak, editor-in-chief and in-house counsel for Breitbart’s website, Breitbart.com, posted a statement confirming his death.

“Andrew passed away unexpectedly from natural causes shortly after midnight this morning in Los Angeles,” the statement read. “We have lost a husband, a father, a son, a brother, a dear friend, a patriot and a happy warrior.”

Breitbart was the first to post Weiner’s infamous Twitter photos last year, in which the married congressman appeared barechested and in his underpants in pictures sent to a woman online. Weiner eventually stepped down amid the scandal.
