The official says Obama discussed the proposal Tuesday with French President Francois Hollande and British Prime Minister David Cameron. France's foreign minister says France will float a resolution in the U.N. Security Council aimed at forcing Syria to make public its chemical weapons program, place it under international control and dismantle it.
Obama has said the proposal marks a potential breakthrough that could halt plans for a U.S. military strike, though he said the details remain unclear.
The official requested anonymity because the officials was not authorized to discuss the private conversations by name.
