Jerome Corsi is an American author and political commentator known for promoting far-right conspiracy theories. Born in 1946, Corsi holds a PhD from Harvard University and first gained prominence co-authoring Unfit for Command during the 2004 U.S. presidential election, which attacked John Kerry’s military service. He later became a leading figure in the false "birther" movement, questioning President Barack Obama's citizenship, and has written extensively about globalism, the Deep State, and QAnon. Corsi has been associated with InfoWars and was investigated in 2018 during the Trump-Russia inquiry for his ties to WikiLeaks, although he was not charged. Despite widespread criticism and debunking of his claims, he continues to influence conspiracy theory circles through his writings and media appearances.
