Middle East retailing giant Landmark Group, which he founded and chairs, suspended sales of all Trump-branded products last December after the U.S. presidential candidate made anti-Muslim remarks. With estimated revenue of $6 billion, Landmark, which his wife Renuka helps him run, has more than 2,400 stores spread across the Middle East, Africa and India. It recently inked an agreement to open new stores with Abu Dhabi's upcoming Reem Mall and also with Oman's Muscat Grand Mall.
