Newsweek is reporting that the Bush administration has gathered intelligence that indicates Iraqi National Congress leader Ahmed Chalabi has been sharing detailed information about US security and political plans in Iraq to top Iranian officials. Chalabi, whose group still receives $340,000 monthly from US taxpayers, has denied the charges but an aide admitted that he has made regular visits to Tehran to meet with Iran’s supreme religious leader Ayatollah Ali Khamenei and his top national-security aide.
