Chief Pentagon Spokesman Sean Parnell said in a statement late Monday that, at Trump's direction, the Department of Defense "is sending additional defensive weapons to Ukraine to ensure the Ukrainians can defend themselves while we work to secure a lasting peace and ensure the killing stops."

Russian President Vladimir Putin told US President Donald Trump during a phone call that Moscow will not give up its goals in Ukraine as any remaining hope for a cease-fire in the more than 40-month war crumbles.
