U.S. President Donald Trump said Tuesday that Ukraine could win back all of its territory from Russia, in an astonishing turnaround on the war after meeting President Volodymyr Zelenskyy.

Trump's suggestion that Kyiv could win, with financial support from EU and NATO, marks an extraordinary shift after months of saying Ukraine would likely have to cede land to its larger neighbor.

Zelenskyy hailed Trump's comments as a "big shift."
