Breitbart News is a conservative, American news and opinion website founded in 2007 by Andrew Breitbart. It gained significant prominence during the 2016 U.S. presidential election under the leadership of Steve Bannon, who served as its executive chairman and later as a White House strategist. The outlet is known for its nationalist, populist, and right-wing editorial stance. It has faced criticism from various media observers and academics for publishing conspiracy theories, intentionally misleading stories, and content described as xenophobic or racist. While it remains a notable voice in conservative media, it has experienced fluctuations in readership and influence over the past decade.
