U.S. Secretary of State Marco Rubio refused to identify any concessions offered by Russian President Vladimir Putin during ongoing Russia-Ukraine peace negotiations, telling multiple Sunday television programs that disclosing specifics could jeopardize the talks. His appearances came two days after President Donald Trump’s face-to-face meeting with Putin at Joint Base Elmendorf-Richardson in Anchorage, Alaska. Rubio said the administration had “identified potential areas of agreement” but cautioned that “big areas of disagreement” remain. While he withheld details of Moscow’s position, Trump later outlined two concessions he believes Kyiv must accept, signaling that Washington is pressing both sides to compromise. Ukrainian President Volodymyr Zelensky is expected at the White House on Monday for further discussions, joined by leaders from Britain, France and Germany. The flurry of diplomacy underscores the administration’s effort to convert preliminary understandings into a broader accord that would end the nearly four-year war, though the negotiating parameters remain largely confidential.
