Donald Trump's self-styled "fabulous world of golf" faces the possibility of being a lot less fabulous after his disparaging remarks about illegal immigrants.

Trump, the billionaire real estate developer and 2016 Republican presidential candidate, has his trademark name on numerous buildings around the world. But he is perhaps proudest of his involvement in golf and is considered a savior in many circles for investing in the industry at a time when many golf courses are closing due to financial pressures.

Trump now has 18 courses, with a string of major tournaments lined up at some. A solid player himself, he boasts a handicap in the single digits. For a while, the Golf Channel ran a regular show called Donald J. Trump's Fabulous World of Golf.
