Exclusive: Trump reviews plan to halt US military aid to Ukraine unless it negotiates peace with Moscow

Two key advisers to Donald Trump have presented him with a plan to end Russia's war in Ukraine -- if he wins the presidential election -- that involves telling Ukraine it will only get more U.S. weapons if it enters into peace talks.

The United States would at the same time warn Moscow that any refusal to negotiate would result in increased U.S. support for Ukraine, retired Lieutenant General Keith Kellogg, one of Trump's national security advisers, said in an interview.

Under the plan drawn up by Kellogg and Fred Fleitz, who both served as chiefs of staff in Trump's National Security Council during his 2017-2021 presidency, there would be a ceasefire based on prevailing battle lines during peace talks.
