Multiple U.S. senators claimed on Saturday that Secretary of State Marco Rubio informed them the peace plan to end the Russia-Ukraine war was not authored by the United States, even as President Donald Trump barrels ahead with a Thanksgiving deadline for Kyiv to accept its terms.

Rubio discussed the controversial 28-point peace plan during a call with a bipartisan delegation of lawmakers at the Halifax International Security Forum on Saturday, including Sens. Mike Rounds (R-SD), Angus King (I-ME), and Jeanne Shaheen (D-NH).
