Ukrainian President Petro Poroshenko addressed a joint meeting of Congress today, thanking lawmakers for their support of Kiev in its fight against Russian-backed separatists.
Freedom, Poroshenko said, is "at the core of Ukrainian existence.
"We have an unbreakable will to live free," he said, saying his nation was "at the center of the most heroic story of the last decade."
Calling Russia's annexation of Crimea a "most cynical act of treachery," Poroshenko thanked lawmakers for standing by his government.
