Donald Trump's envoys Steve Witkoff and Army Secretary Dan Driscoll are leading US efforts in the talks about peace in Ukraine, despite lacking diplomatic experience. Witkoff, a real estate investor and Trump confidant, met Putin in August and faces criticism for pro-Kremlin views. Driscoll, 39, presented a leaked 28-point peace plan in Kyiv and is close to VP JD Vance. On Russia's side, key figures include Kirill Dmitriev, head of the state investment fund, and veteran advisor Yuri Ushakov.
