The sources said the background check concerned Mr. Obama's years in Jakarta. In Indonesia, the young Obama was enrolled in a Madrassa and was raised and educated as a Muslim. Although Indonesia is regarded as a moderate Muslim state, the U.S. intelligence community has determined that today most of these schools are financed by the Saudi Arabian government and they teach a Wahhabi doctrine that denies the rights of non-Muslims.
Although the background check has not confirmed that the specific Madrassa Mr. Obama attended was espousing Wahhabism, the sources said his Democratic opponents believe this to be the case--and are seeking to prove it. The sources said the opponents are searching for evidence that Mr. Obama is still a Muslim or has ties to Islam.
