During the press conference, U.S. President Donald Trump added that he was "a little bothered" by Zelensky's words regarding "constitutional approval" for land swaps as part of a potential peace agreement.

A diplomatic scramble unfolded Saturday after President Donald Trump announced he would meet his Russian counterpart, Vladimir Putin, next week in Alaska, as European leaders rushed to understand the terms of the meeting and ensure Ukraine was not being left out of discussions about its future.

Kyiv has repeatedly rejected any so-called "land swap" which would be against the Ukrainian Constitution. Zelensky's comments on Saturday acknowledge Trump's role in any peace deal with the summit but again reject the chances that Ukrainian land can be traded for peace.
