Senate Ukraine aid blocked by Republicans for months as McConnell ties it to border security

Senate Republicans, led by Mitch McConnell, block a $106 billion emergency supplemental package for Ukraine, Israel, and Taiwan, demanding that border security provisions be attached before any foreign aid can pass. The standoff begins in December 2023 and lasts through February 2024, when the bipartisan Lankford-Murphy-Sinema border deal collapses under pressure from Donald Trump. Ukraine suffers months of artillery shell shortages while the funding gap persists. The blockade marks a historic shift in Republican foreign policy, with McConnell warning it could cost Ukraine the war.
