US State Department spokesperson Tammy Bruce announced on Tuesday that Secretary of State Marco Rubio has canceled his planned visit to London, where discussions about the Ukraine conflict are scheduled.
"While the meetings in London are still occurring, he will not be attending," the spokesperson added. Special Envoy Keith Kellogg will attend in his place. Previously, Rubio warned that the US would withdraw from Ukraine peace negotiations "within days" if there were no signs of progress.
US President Donald Trump's special envoys Steve Witkoff and Keith Kellogg are set to engage with foreign ministers and security advisers from France, Germany, the UK, and Ukraine as he seeks an agreement to end Russia's military offensive.
