He gained notoriety in 2008 for claiming to have engaged in drug use and a sexual encounter with Obama in 1999.
Sinclair has a criminal history, including convictions for forgery, fraud, and larceny.
His allegations against Obama have been widely discredited and dismissed.
Sinclair wrote a book titled "Barack Obama & Larry Sinclair: Cocaine, Sex, Lies & Murder?" elaborating on his claims.
His controversial claims did not significantly impact Obama's presidential campaign.
Mainstream media and political observers generally regarded Sinclair's allegations as baseless and politically motivated.
Despite his criminal background, Sinclair has persisted in reiterating his allegations in recent interviews.
Former Fox News host Tucker Carlson shared a clip of an interview with Sinclair, reigniting the controversy.
Larry Sinclair's notoriety largely stems from his unsubstantiated claims against Barack Obama, which continue to be widely disbelieved.
