With a chance to make a better second impression in the Oval Office, gratitude diplomacy was front and center for Zelenskyy. In addition to thanking the president six times, Zelenskyy extended gratitude to Melania Trump for personally writing to Russian President Vladimir Putin to think about the Ukrainian children and urge peace.

Trump made the announcement after a day of talks with Ukraine's Volodymyr Zelenskyy and a delegation of top European officials. He said he'd meet with the two leaders afterward, but did not say when.

President Trump is working to coordinate a meeting between Russian President Vladimir Putin and Ukrainian President Volodymyr Zelenskyy, which would be the first face-to-face interaction between the two leaders since Russia invaded Ukraine more than three years ago.
