Ukraine's President Volodymyr Zelensky called on the US to provide more funding to help his forces counter Russia, and invited former US President Donald Trump to fly in to see the scale of the conflict for himself.
Zelensky said American soldiers could eventually be pulled into a greater European conflict with Russia if Washington did not step up support.
"If Russia will kill all of us, they will attack NATO countries and you will send your sons and daughters [to fight]," Zelensky said according to a transcript of an interview with NBC's 'Meet the Press' airing on Sunday.
US President Joe Biden, a Democrat, has pressed the US Congress to pass a $106 billion supplemental spending bill, with the bulk of the money going to bolster Ukraine's defenses and the remainder split among Israel, the Indo-Pacific and border enforcement.
The Republican-led US House of Representatives has instead put forward its own funding plan. It passed a bill last week to provide $14.3 billion in aid to Israel, but did not include any increase in aid for Ukraine.
US Senator Chuck Schumer, majority leader of the Democratic-controlled Senate, said he would not bring the House bill to a vote and Biden has vowed to veto it.
In the interview airing on Sunday, Zelensky invited former US President Donald Trump, a Republican, to visit Ukraine and see the fallout of the conflict initiated by Russia's President Vladimir Putin in February 2022.
Trump, who is seeking reelection in 2024 and is the leading candidate for his party's presidential nomination, has been sharply critical of US support for Kyiv and has said he could end the war in 24 hours if reelected.
"If he can come here, I will need ... 24 minutes to explain to President Trump that he can't manage this war," Zelensky said. "He can’t bring peace because of Putin."
