The US Senate plans to vote on aid to Ukraine in early December.

US Senate Majority Leader Chuck Schumer plans to hold a vote on President Joe Biden’s request to provide billions in aid to Ukraine and Israel as early as December 4.

According to Politico, Schumer’s statement, released on Sunday, puts pressure on lawmakers to strike a deal on border security that could be combined with much-needed aid to the two US allies. Schumer called the border requirement “the biggest obstacle” to allocating new funds for Ukraine’s defense against Russia and Israel’s war with Hamas.

“Nothing would make autocrats like Putin or Xi happier right now than to see the US wavering in support of the Ukrainian people and its military,” Schumer wrote in his letter, adding that “This is not just about Ukrainian or Transatlantic security, it’s about American security as well because an unchecked Putin would be an emboldened Putin.”
