Under Bannon, Breitbart went to bat for Ailes several years back against Ailes biographer Gabriel Sherman by publishing anonymous smears. The site, however, also broke with Ailes’ Fox News in August 2015 by siding with candidate Trump in his feud with then-prime-time star Megyn Kelly. Still, Breitbart again came to his defense in July 2016 as he faced widespread sexual harassment allegations. Bannon also was speaking to Ailes during his final days at Fox News, according to Green’s biography of Bannon, and as the visionary media executive plotted a comeback before his death in May.
