Steve Witkoff started out as a New York lawyer, until a late night encounter with Donald Trump in a sandwich shop inspired him to move into real estate. Known as "Smoking Steve", he has amassed a property empire worth millions, become friends and golf buddies with Trump, and has now been appointed as his Middle East Envoy and go-to international negotiator and trouble shooter.

To his critics he's dangerously unqualified and out of his depth. To his supporters, he's the straight-talking fresh pair of eyes needed to resolve deeply entrenched conflicts.
