WASHINGTON, Jan 4 - Senators on Sunday released a highly anticipated $118 billion package that pairs border enforcement policy with wartime aid for Ukraine, Israel and other U.S. allies, setting off a long-shot effort to push the bill through heavy skepticism from Republicans, including House Speaker Mike Johnson.

The proposal could be the best chance for President Joe Biden to resupply Ukraine with wartime aid — a major foreign policy goal that is shared with both the Senate’s top Democrat, Sen. Chuck Schumer, and top Republican, Sen. Mitch McConnell, The Associated Press reported. The Senate was expected this week to hold a key test vote on the legislation, but it faces a wall of opposition from conservatives.

With Congress stalled on approving $60 billion in Ukraine aid, the U.S. has halted shipments of ammunition and missiles to Kyiv, leaving Ukrainian soldiers outgunned as they try to beat back Russia’s invasion.

Biden said in a statement that the Senate proposal “allows the United States to continue our vital work, together with partners all around the world, to stand up for Ukraine’s freedom and support its ability to defend itself against Russia’s aggression.”

And on the border, Biden said that the immigration system has been broken for too long, and it’s time to fix it. “It will make our country safer, make our border more secure, treat people fairly and humanely while preserving legal immigration, consistent with our values as a nation,” Biden said.

The new bill would also invest in U.S. defense manufacturing, send $14 billion in military aid to Israel, steer nearly $5 billion to allies in the Asia-Pacific, and provide humanitarian assistance to civilians caught in conflicts in Ukraine and Gaza.

In a call with reporters after releasing the legislation, Schumer said he has never worked so closely with McConnell. He called the bill a “monumental step” toward strengthening national security at home and abroad.

Without the Ukraine aid, Schumer said, he believes Russian President Vladimir Putin “could be rolling over Ukraine and even into Eastern Europe.”

McConnell said in a statement that the Senate must be “prepared to act.”

“America’s sovereignty is being tested here at home, and our credibility is being tested by emboldened adversaries around the world,” McConnell said. “The challenges we face will not resolve themselves, nor will our adversaries wait for America to muster the resolve to meet them.”

In a bid to overcome opposition from House Republicans, McConnell had insisted last year that border policy changes be included in the national security funding package. The bill would overhaul the asylum system at the border with faster and tougher enforcement, as well as give presidents new powers to immediately expel migrants if authorities become overwhelmed with the number of people applying for asylum.

However, in an election-year shift on immigration, Biden and many Democrats have embraced the idea of strict border enforcement, while Donald Trump and his allies have criticized the proposed measures as insufficient.

Republicans have also been reluctant to give Biden a political win on an issue they see as one of his biggest vulnerabilities. They have argued that presidents already have enough authority to curb illegal border crossings — a stance that would ensure immigration remains a major issue in the presidential election. But at the same time, House Republicans have also pushed for their own, stricter version of border security legislation.

Johnson, a Republican of Louisiana, told NBC’s “Meet the Press” on Sunday that he had tried to involve House Republicans directly in the Senate’s negotiation, but was rebuffed. He added he was unaware of the bill’s details, but thought the solution to border problems should be a House proposal of hardline immigration measures.

“What we’re saying is you have to stem the flow,” Johnson said. He also made it clear that he — not Trump — would decide whether to bring the bill to the floor if it passes the Senate.

But in a further sign that Johnson is resistant to the Senate package, he indicated Saturday that the House will vote on a separate package of $17.6 billion of military aid for Israel — a move that allows House Republicans to show support for Israel apart from the Senate deal.

It is still unclear if the bill will pass in the Senate. Senate Republicans have been divided on the bill, with several in McConnell’s ranks arguing that it isn’t strong enough. Some said they would vote against it.

“I will not support this deal,” said Sen. Marsha Blackburn, R-Tenn, after the legislation was released. She said the Senate should take up the House bill.

Still, Sen. Kyrsten Sinema, an Arizona independent who negotiated the border proposal, told CBS’ “Face the Nation” that the legislation would be “realistic, pragmatic, and the strongest solution to our border crisis in my lifetime.” (ap/ez)
