Ukrainian president Volodymyr Zelenskyy is seeking direct support from US senators as Congress faces a critical vote on Ukraine aid. The White House has warned that the approved aid will be exhausted by the end of the year, leaving Ukraine vulnerable to Russia. Zelenskyy, appearing via videolink, addresses the Senate during a classified briefing on the conflict. Additionally, Zelenskyy’s chief of staff and defense minister, alongside Ukraine’s parliamentary speaker, personally lobby in Washington. The lobbying efforts coincide with closed-door briefings involving top US officials. However, the politics surrounding the aid package remain challenging, with Senate Republicans tying funding support to measures addressing the migrant crisis at the southern border. Democrats, on the other hand, walk out of negotiations. The House vote is expected to be equally demanding, with Republicans expressing concerns about the lack of a clear strategy in Ukraine.
