"I am encouraged by your recent acknowledgement that "what Kushner did crossed the line of ethics' and your repeated assertions that our Committee is "investigating foreign nationals' attempts to target and coerce high-ranking U.S. officials' family members by providing money or other benefits in exchange for certain actions.' . . . In light of these concerns, I urge you to pursue a serious and objective investigation by issuing a subpoena to Affinity and requiring the firm to comply with my February 15, 2023, request for documents regarding its receipt of billions of dollars from Gulf monarchies shortly after Mr. Kushner left a senior White House position he used to reshape U.S. foreign policy toward Saudi Arabia and the Middle East in Saudi Arabia's favor--a request you have thus far allowed Mr. Kushner to ignore and defy."
