Just weeks removed from playing a critical role in the Israel-Hamas ceasefire, President Donald Trump’s Middle East envoy, Steve Witkoff, now appears to have a major role in the administration’s efforts to end Russia’s war in Ukraine.

Witkoff, who had no diplomatic experience prior to Trump’s victory last November, was one of three senior administration officials who met with senior Russian leaders in Saudi Arabia on Tuesday. Witkoff, Secretary of State Marco Rubio, and national security adviser Mike Waltz led the U.S. delegation.
