"John, heard this second hand but more than once. Seems Erdogan faction is making substantial investments in U.S. to counter opposition (CHP, Kurds, Gulenists etc.) outreach to policymakers and USG. Am told that the Erdogan crew also tries to make inroads via donations to Democratic candidates, including yours," Cheng said in an email addressed to Clinton's campaign chair John Podesta on August 20, 2015.
In the same letter, Cheng named two people, Turkish-American national community leader and businessman Mehmet Celebi and executive vice president of the Turkish Heritage Organization Ali Cinar, who Podesta should be aware of and expressed his willingness to elaborate the issue on the phone.
