Washington — U.S. President Joe Biden will discuss top domestic and foreign policy priorities with President-elect Donald Trump when the two meet Wednesday, and will urge him not to abandon Ukraine, national security adviser Jake Sullivan said Sunday. Republican Trump will take office on Jan. 20 after defeating Vice President Kamala Harris in the Nov. 5 presidential election. Biden invited Trump to come to the Oval Office on Wednesday, the White House said. In an interview on CBS News’ “Face the Nation” show, Sullivan said Biden’s top message will be his commitment to ensure a peaceful transfer of power, and he will also talk to Trump about what’s happening in Europe, in Asia and the Middle East. “The president will have the chance to explain to President Trump how he sees things, where they stand, and talk to President Trump about how President Trump is thinking about taking on these issues when he takes office,” Sullivan said. While Sullivan did not specify which topics the two would discuss, their conversation will almost certainly feature Ukraine’s war with Russia, which Trump has pledged to end swiftly, although he did not say how. “President Biden will have the opportunity over the next 70 days to make the case to the Congress and to the incoming administration that the United States should not walk away from Ukraine, that walking away from Ukraine means more instability in Europe,” Sullivan said. When asked if that means Biden will ask Congress to pass legislation to authorize more funding for Ukraine, Sullivan deferred. “I’m not here to put forward a specific legislative proposal. President Biden will make the case that we do need ongoing resources for Ukraine beyond the end of his term,” Sullivan said. Ukraine funding Washington has provided tens of billions of dollars’ worth of U.S. military and economic aid to Ukraine since it was invaded by Russia in February of 2022, funding that Trump has repeatedly criticized and rallied against with other Republican lawmakers. Sullivan’s comments came as Ukraine attacked Moscow on Sunday with at least 34 drones, the biggest drone strike on the Russian capital since the beginning of the war. Trump insisted last year that Russian President Vladimir Putin never would have invaded Ukraine if he had been in the White House at the time. He told Reuters Ukraine may have to cede territory to reach a peace agreement, something the Ukrainians reject, and Biden has never suggested. Ukraine President Volodymyr Zelenskyy said Thursday he was not aware of any details of U.S. President-elect Donald Trump’s plan to end the Ukraine war quickly and that he was convinced a rapid end would entail major concessions for Kyiv. According to the Government Accountability Office, Congress appropriated over $174 billion to Ukraine under Biden. The pace of the aid is almost sure to drop under Trump with Republicans set to take control of the U.S. Senate with a 52-seat majority. Control of the U.S. House of Representatives in the next Congress is not yet clear with some votes still being counted. Republicans have won 213 seats, according to Edison Research, just shy of the 218 needed for a majority. If Republicans win both chambers, it will mean most of Trump’s agenda will have a significantly easier time passing through Congress. Republican U.S. Senator Bill Hagerty, a Trump ally who is considered a top contender for secretary of state, criticized U.S. funding for Ukraine in a CBS interview. “The American people want sovereignty protected here in America before we spend our funds and resources protecting the sovereignty of another nation,” Hagerty said. The 2-1/2-year-old war in Ukraine is entering what some officials say could be its final act after Moscow’s forces advanced at the fastest pace since the early days of the war. Any fresh attempt to end the war is likely to involve peace talks of some kind, which have not been held since the early months of the war. Moscow’s forces occupy around a fifth of Ukraine. Russia says the war cannot end until its claimed annexations are recognized. Kyiv demands all of its territory back, a position that has largely been supported by Western allies.
