Laura Elizabeth Loomer is an American far-right political activist, conspiracy theorist, internet personality, social media influencer, journalist, and former congressional candidate. Born on May 21, 1993, in Tucson, Arizona, she rose to prominence through undercover journalism stunts and provocative content with right-wing media organizations including Project Veritas and Rebel News (formerly The Rebel Media), where she targeted perceived liberal biases in media and academia. Loomer, who is Jewish, has been a vocal supporter and informal advisor to former President Donald Trump, with reports crediting her with influencing his administration's policies on issues like immigration and national security, including reportedly contributing to the 2017 travel ban targeting Muslim-majority countries. She has promoted numerous conspiracy theories, including claims about the Parkland school shooting being a hoax, 9/11 being an inside job, election fraud, and COVID-19 vaccines, alongside anti-Muslim rhetoric, anti-immigrant views, and controversial statements about race, leading to widespread criticism for Islamophobia and extremism.

Loomer has run twice as a Republican candidate for the U.S. House of Representatives in Florida: in 2020 for Florida's 21st Congressional District (finishing third) and in 2022 for the 11th District (placing second in the primary but losing the nomination). Her career spans media and politics; she hosts the podcast 'Loomer Unleashed,' runs Illoominate Media LLC, and authored the 2023 memoir 'Loomered: How I Became the Most Banned Woman in the World.' She has been banned from multiple social media platforms like Twitter (now X), Facebook, and Instagram for violating hate speech policies, with Twitter's 2018 ban citing her promotion of violence and bigotry, though she was reinstated on X under Elon Musk's ownership, where she has amassed over a million followers.

Controversies define much of Loomer's public image; she has been accused of white nationalism, anti-Semitism (despite her Jewish heritage), and spreading disinformation. Her activism often involves provocative actions, such as disrupting events (e.g., a 2017 Shakespeare in the Park event), chaining herself to Twitter's doors in 2018 to protest her ban, and facing legal troubles including a 2017 arrest for disrupting a New York event (charges dropped). Critics, including the Anti-Defamation League, have condemned her for fueling hate, while supporters view her as a fearless truth-teller. Despite setbacks, she remains influential in conservative circles, attending Trump rallies and advising on campaign strategies, though she has faced backlash from mainstream Republicans for her inflammatory rhetoric.
