Rand Paul stalls Senate passage of $40 billion in Ukraine aid

Kentucky Republican Sen. Rand Paul defied leaders of both parties Thursday and delayed until next week Senate approval of an additional $40 billion to help Ukraine and its allies withstand Russia's three-month old invasion.

With the Senate poised to debate and vote on the package of military and economic aid, Paul denied leaders the unanimous agreement they needed to proceed. The bipartisan measure, backed by President Joe Biden, underscores U.S. determination to reinforce its support for Ukraine's outnumbered forces.

The legislation has been approved overwhelmingly by the House and has strong bipartisan support in the Senate. Final passage is not in doubt.
