President of Ukraine Volodymyr Zelenskiy visited with US senators on Capitol Hill on Tuesday, trying in vain to maintain military assistance while fighting Russia, but some Republicans were unimpressed.

Republicans have been hesitant to approve Democratic President Joe Biden’s financing request, which would provide $61.4 billion to Ukraine.

Following their discussion with Zelenskiy, Republican Speaker of the House of Representatives Mike Johnson stated that Biden’s administration has to give more information about how the funds would be used.

“What the Biden administration seems to be asking for is billions of additional dollars with no appropriate oversight, no clear strategy to win and with none of the answers that I think the American people are owed,” he said after meeting with Zelenskiy.

Other Republicans questioned whether additional aid would help Ukraine defeat Russia after a summer offensive that has failed to yield clear gains.

“I know everyone wants Ukraine to win, I just don’t see it in the cards,” Republican Senator Ron Johnson said.

Heading into winter, with tens of thousands of Ukrainians dead, a yawning budget deficit and Russian advances in the east, Zelenskiy is asking Washington to provide badly needed support.
