Not long before a major crisis ripped through the Middle East, pitting the United States and a bloc of Gulf countries against Qatar, Jared Kushner’s real estate company had unsuccessfully sought a critical half-billion dollar investment from one of the richest and most influential men in the tiny nation, according to three well-placed sources with knowledge of the near transaction. Qatar is facing an ongoing blockade led by Saudi Arabia and the United Arab Emirates, and joined by Egypt and Bahrain, which President Trump has taken credit for sparking. Kushner, meanwhile, has reportedly played a key behind-the-scenes role in hardening the U.S. posture toward the embattled nation.
