His website, Big Journalism, which first reported the news, says Breitbart died of natural causes.
“We have lost a husband, a father, a son, a brother, a dear friend, a patriot and a happy warrior,” says the site in a statement. “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.”
Conservative blogger Michelle Malkin confirmed the news, calling Breitbart’s death a “devastating loss.”
He is survived by his wife Susannah, and his four children.
