How US keeps funding Ukraine's military even as it says it's out of money

US President Joe Biden on December 12 touted a new military aid package worth $200 million for Ukraine. Money is dwindling. But the announcement of more weapons being sent to Kyiv just underscores the complexity of the funding. So has the money run out? Or are there still a few billion dollars floating around? It’s complicated. The US has already sent Ukraine $111 billion in weapons, equipment, humanitarian assistance and other aid since Russian President Vladimir Putin launched his invasion more than 21 months ago.
