AUSTIN, Texas, Sept. 11 (UPI) -- Actor Charlie Sheen has appeared on radio and YouTube to urge U.S. President Barack Obama to reopen the investigation into the Sept. 11, 2001 terror attacks.

The "Two and a Half Men" star Tuesday published on radio talk show host Alex Jones's Infowars.com and PrisonPlanet.com Web sites a fictional account of a meeting with the president in which Sheen confronts Obama about what Sheen alleges is a cover-up surrounding 9/11.

In his letter, Sheen requests a real meeting with Obama. The actor followed the letter up by appearing in a YouTube video telling Obama he ought to "be on the right side of history" by reopening an investigation into 9/11, while claiming the majority of the 9/11 Commission members have publicly dismissed the official government version of the attacks as a deception, with former senator and commission member Max Cleland labeling the government response to the commission's questions as "disgusting" and "a scam."

Sheen highlights several issues in the video, including the collapse of WTC 7 in Manhattan. He also cites multiple reports from firefighters, police, first responders and others who were at Ground Zero and who all described explosions before the collapse of the Twin Towers and Building 7.

"We have questions Mr. President, lots of questions. ... People of the United States and the world demand the truth, sir," Sheen said, adding that Obama has the power and the responsibility to initiate "a truly independent Congressional investigation into the events of 9/11 as well as its aftermath."

Sheen also was scheduled to discuss the matter live on "The Alex Jones Show" Friday, the eighth anniversary of the Sept. 11 attacks, which left more than 3,000 people dead in New York, Washington and Pennsylvania.
