A man named Larry Sinclair posted a YouTube video alleging that he and President Barack Obama engaged in sexual acts and drug use together in 1999, when Obama was an Illinois State Senator. He claims that then-State Senator Obama procured powdered cocaine for Sinclair, and crack for himself (which Obama allegedly smoked). Sinclair also attests that their drug use was followed by sex acts that included Sinclair performing fellatio. These acts were alleged to take place in a limousine.http://www.huffingtonpost.com/archive/236/blog/w/joseph_minton_amann_and_tom_breuer/media_drunk_tank_dreams_of_my_10926.html

Whitehouse.com (not an official government site) offered to pay Sinclair $10,000 to take a polygraph test and an additional $100,000 if he passed. Sinclair agreed to the terms and took the test on February 25, 2008. According to reports, a former president of the American Polygraph Association determined that Sinclair's results indicated "deception," with regard to the drug and sex claims.Cleveland Leader: [http://www.clevelandleader.com/node/4799 Larry Sinclair Polygraph Test Indicates "Deception" In Obama Claims

Sinclair repeated his claims at the National Press Club on June 18, 2008. Asked whether he was receiving money from anyone connected with the Republican Party, Sinclair said, "I am not connected with any party... nor are any parties contributing to the cost or the expense of this." Afterward, Sinclair—who was wanted in Colorado on theft and forgery charges—was presented with an arrest warrant by Washington DC police, handcuffed and taken into custody, according to reports.YouTube: Sen.
