US Secretary of State Marco Rubio accused President Volodymyr Zelensky of lying about claims that the US pressured Ukraine to cede the Donbas region for security guarantees.During a G7 meeting in Paris, Rubio clarified that the US merely conveyed Russian demands without endorsing them, noting that security agreements would only follow a total end to the war.The disagreement occurs as the US considers prioritizing military resources for its conflict with Iran, including the recent relocation of Patriot missiles from Europe.
