The Pentagon is poised to send $1 billion in new military aid to Ukraine, U.S. officials said Tuesday as the Senate moved ahead on long-awaited legislation to fund the weapons Kyiv desperately needs to stall gains being made by Russian forces in the war.

The decision comes after months of frustration, as bitterly divided members of Congress deadlocked over the funding, forcing House Speaker Mike Johnson to cobble together a bipartisan coalition to pass the bill. The $95 billion foreign aid package, including billions for Israel and Taiwan, passed the House on Saturday, and the Senate approved it Tuesday. President Joe Biden said he would sign it Wednesday.
