U.S. President Donald Trump and Russian President Vladimir Putin spoke by phone for about an hour on Sept. 8, Russian state news agency Tass reported the same day, citing Kremlin aide Yuri Ushakov. The call took place just days after U.S. envoy Steve Witkoff and Trump's son-in-law Jared Kushner completed an inconclusive round of talks in Moscow and Kyiv, with Russia resuming large-scale strikes on Kyiv immediately after the U.S. delegation's departure.
