The real estate mogul and Trump golf buddy who is negotiating the fate of Gaza and Ukraine

When Joe Biden was in the White House, the go-to figure for Gaza and Ukraine was Antony Blinken, the then Secretary of State. But now it's not the name of Marco Rubio, the current head of US diplomacy, that comes up every time negotiations are mentioned. Two of the most important international portfolios for the new Donald Trump administration fall to someone else: Steve Witkoff, a New York real estate mogul and old friend and golf partner of the president. A person with no diplomatic experience.
