Former Republican presidential nominee Mitt Romney has rejoined the board of directors of Marriott International, the parent company of one of the world's largest hospitality, hotel chains, and food services companies, owned by a devout Mormon family. "We are delighted that Gov. Romney has agreed to rejoin our board, on which he has served with distinction twice before," J.W. Marriott, Jr., the company's executive chairman, said in a statement on Monday.
