Nobody in Washington, Democrat or Republican, appears to have questioned how Khawaja earned his money, and what exactly Khawaja might hope to gain from his political giving is not entirely clear. The records reviewed by the AP show that Khawaja has pursued foreign business deals, including an investment by a United Arab Emirates-controlled wealth fund, a prospective deal with an Iranian bank and a potential business arrangement with Lebanon. Some U.S. senators he has supported are on the banking committee, which writes laws governing his industry.
