A former Lehman trader has accused Goldman Sachs and other Wall Street firms of laundering jihad money. In a May 5 interview, Joy Brighton singled out the giant bailed-out investment bank as "the money manager of choice for Iran, Saudi Arabia, the Taliban and Al-Qaeda."

"Investment firms like Goldman and others have been creating mini Islamic banks under their umbrellas, which look and act remarkably like Iranian Banking. They are hiring politically powerful Sheiks to help manage these businesses, which include the creation of derivative financial structures, which subsidize radical mosques, Islamic centers & political action groups through a 'charity' donation system adopted in 1978 by Ayatollah Khomeini." Brighton charged..

The U.S. Treasury has already identified 27 Islamic "charities" as front-groups for terrorism. Nevertheless, Americans with large pension, endowment, and hedge funds in their portfolios may unwittingly be investing in radical Islamic groups such as Hamas, she added.

"The aggressive promotion of Shariah banking by Imams, in radical mosques and university campuses throughout Europe and America, fits into the strategy of legitimizing and imposing all of Shariah law, bit by bit, into the fabric of Western legal systems, eventually to force out secular law."
