Big League Politics is a far-right American media website which traffics in conspiracy theories and was founded by former Breitbart News employees. The site was announced in 2017 by one of its founders as an investigative outfit. In early 2018, Big League Politics was acquired by Mustard Seed Media which is owned by Reilly O'Neal and Noel Fritsch. Its editor-in-chief is former Breitbart reporter Patrick Howley. The Wall Street Journal describes the website as "backed by Republican operatives".
The website has promoted conspiracy theories, on subjects such as QAnon and the murder of Seth Rich. The New York Times described Big League Politics as "an obscure right-wing news site [...] which has promoted conspiracy theories and written favorably about white nationalist candidates." Huffington Post said it is intended for "people who find Breitbart too reasonable" and has defended white supremacists, including after the neo-Nazi "Unite the Right" 2017 Charlottesville rally.
