“Due to security concerns, we had to move the Larry Sinclair polygraph up a few days,” reports WhiteHouse.com. “We conducted it in secret today and the picture to the left is from from one of the two arduous polygraphs Sinclair underwent today.”

According to the Web site, “the process took four grueling hours, testing Sinclair’s claims of sex and drug use separately and also including a drug screening to ensure that Sinclair didn’t enlist any chemical assistance.”

Sinclair was paid $10,000 for his participation and has pledged to donate most of the funds to charity.

The site reports that the “results are being confirmed by a second expert” and that there will be “conclusive word” of the results on Monday or Tuesday. Video of the process will be hosted on the site.
