Brian T. Carroll

On April 5, 2019, Carroll declared his candidacy for President of the United States in the 2020 United States presidential election, seeking the nomination of the American Solidarity Party. He won the nomination at the online party convention, and chose ASP chair Amar Patel as his running mate.

Carroll ran for California's twenty-second congressional district in 2018, campaigning against Republican incumbent Devin Nunes and Democrat Andrew Janz. This was a contentious election due to Nunes' role in the 2018 Trump–Russia investigation. Carroll received 1,591 votes in the top-two primary, placing fifth in a field of six candidates. During the general election (after Carroll's elimination), Janz claimed that Carroll had endorsed him; Carroll publicly denied this claim.

Carroll received his bachelor's degree in history from UCLA and earned a teaching credential at California State University, Los Angeles. He taught junior high history and other subjects in Farmersville, California from 1977 to 1983. During that time, he also wrote for the Valley Voice newspaper, focusing primarily on the local need for public transportation. Carroll has taught students in Colombia and China and traveled extensively throughout Europe and Brazil. As an amateur naturalist, his work has been cited in studies on spiders and insects. In 2008, he returned to teaching in Farmersville.
