A federal judge has reversed some of the convictions of three former Islamic charity leaders who had been accused of duping the U.S. government to hide pro-jihad activities. Samir Al-Monla, Emadeddin Muntasser and Muhammed Mubayyid were convicted in January of conspiracy to defraud the United States, tax code violations and making false statements. A federal judge in Worcester overturned conspiracy charges against the men Tuesday, as well as the tax-code violations against Al-Monla and Muntasser. The judge said prosecutors did not prove the men tried to hide information from the Internal Revenue Service about Care International Inc., which is now defunct. US District Court Judge Dennis Saylor IV let stand Muntasser's conviction on making false statements, as well as the other charges against Mubayyid. Al-Monla, who was cleared of all charges, was released Tuesday.
