Republican senators in the United States have blocked $106 billion in new funding for Ukraine and Israel and rejected appeals from President Joe Biden, angered by the exclusion of immigration reforms they had demanded as part of the package.

Biden had previously warned of dire consequences for Kiev – and a “gift” to Russia’s Vladimir Putin – if Congress did not pass the measure, which includes about $61 billion to help Ukraine, put pressure on Russia as well to maintain aid to Israel and Gaza during the freezing winter months.

“They are prepared to literally bring Ukraine to its knees on the battlefield and harm our national security in the process,” Biden said.

The entire 49-member Republican minority in the upper house voted against the proposal, citing a lack of government action on the estimated 10,000 migrants Crossing every day from Mexico to the USA.

“Everyone has made it very, very clear that we are standing firm. Now is the moment,” Senator James Lankford, a top Republican negotiator on immigration and border issues, told Fox Business before the vote.

“We are completely out of control at the southern border and it is time to solve the problem.”

Citing aid to Israel, independent Senator Bernie Sanders also voted against the bill, which required 60 votes to pass.

Biden has previously implored Republicans over the package, warning that a Russian victory over Ukraine would enable Moscow to attack NATO allies and draw U.S. troops into war.

“If Putin takes Ukraine, he won’t stop there,” Biden said. Putin will attack a NATO ally, he predicted, and then “we’ll have something that we don’t seek and that we don’t have today: American troops fighting Russian troops,” Biden said.

“We can’t let Putin win,” he said.

Border security with Mexico has emerged as a major obstacle to continued assistance to Ukraine, although the White House warned this week that funding allocated to providing aid to Ukraine would prevent this leak until the end of the year.

Republicans in the House and Senate are backing rebuilding a border wall, former President Donald Trump’s signature policy, while deeming large numbers of migrants ineligible for asylum and reviving a controversial policy requiring asylum seekers to come in to remain in Mexico while her immigration case is heard.

Biden said he was willing to make “significant” compromises on the border issue but said Republicans would not get everything they wanted. He did not provide any further details.

“This has to be a negotiation,” he said.

The clock is ticking

Biden, who spoke about Ukraine in a virtual summit with Ukrainian President Volodymyr Zelensky and G7 leaders on Wednesday, said the United States and its allies are ready to support Ukraine in its 22-month war against Russia, which is currently about occupies a fifth of the area, continuing to support Ukrainian territory.

Zelensky warned the G7 that Moscow was betting on a “collapse” of Western unity and said Russia had increased pressure on the front lines of the conflict.

The precarious prospects for the aid package have been clear since a classified Ukraine briefing for senators on Tuesday saw several Republicans leave the country, upset that there was no mention of border security.

Zelenskyj was actually supposed to speak at the meeting via video link, but canceled at the last minute.

Senators from both parties have acknowledged the need to act quickly to reach an agreement as Congress has just a few days left in session until the end of the year.

Republican negotiators were expected to present a new proposal to Democrats after the failed vote.

The president’s willingness to engage directly on the issue carries some political risk, as some Democrats and migrant advocates have urged him to reject sweeping conservative demands on immigration – which they say would amount to closing the border.

Speaker of the House Mike Johnsonwho voted against aid to Kiev before taking office, has made it clear that he will not agree to send more money without “transformative” changes to border policy.

“The American people deserve nothing less,” Johnson said in a statement.

The Louisiana Republican has also said that any aid to Israel must be offset by spending cuts, a policy opposed by Democrats, the White House and most Senate Republicans.

Despite the disagreement over the new funding package, the US provided $175 million worth of aid to Kiev from the dwindling cash supply that has already been approved.
