A bipartisan group of U.S. lawmakers are voicing their opposition to the Trump administration's decision to halt shipments of some air defense missiles and other weapons previously promised to Kyiv.

The U.S. Defense Department (DOD) made the decision to pause the aid deliveries after conducting a review of U.S. munitions stocks, reportedly concerned about dwindling levels of artillery rounds, air defense missiles, and precision munitions.

Among the items being held back from Ukraine are over two dozen Patriot air defense missiles, over two dozen Stinger air-defense systems, precision artillery rounds, Hellfire missiles, drones, and more than 90 AIM air-to-air missiles that Ukraine launches from F-16 fighter jets. The Washington Post reported that the weapons were already in Poland being prepped for delivery to Ukraine.

Republican Rep. Brian Fitzpatrick, the co-chair of the Congressional Ukraine Caucus, lambasted the decision in a post on X.

Fitzpatrick, a staunch ally of Ukraine who has previously visited the front line, said he "will be aggressively looking into this matter and will be demanding accountability."

"We must build up our own Defense Industrial Base here in the U.S. while simultaneously providing the needed assistance to our allies who are defending their freedom from brutal invading dictators. To not do both is unacceptable," the Congressman added.

In a letter to U.S. President Donald Trump about the reported halt of air defense deliveries, Fitzpartick requested an emergency briefing from the White House and DOD on the shipments.

"Ukraine's courage must continue to be met with action, and the United States must continue to lead with clarity and purpose," Fitzpartick wrote.

Another Republican House member, Rep. Michael McCaul, said he is examining "very intensely" whether the Pentagon’s freeze breaches legislation on aid to Ukraine passed in 2024, Politico reported.

As Trump continues to call for a ceasefire from Moscow, McCaul said that the decision comes "at the wrong time."

"If you want to get (Russian President Vladimir Putin) to the negotiating table in good faith, you have to put leverage and pressure on him, and that would be (Senator) Lindsey Graham’s economic sanctions and the flow of weapons," McCaul said. "If you take the flow of weapons out, yeah, then you’re not, you don’t have the leverage over Putin to negotiate."

Other Republican members of Congress have thus far dismissed concerns over the reported halts, stating that they are waiting to be briefed with additional information before speaking about the reports.

On the other side of the isle, Democratic lawmakers have also lambasted the real world implications of halting military aid for Ukraine.

Senator Richard Blumenthal, a member of the Senate Armed Services Committee, said in an interview that more civilians are "going to lose more lives, more people will be maimed and injured — more homes, hospitals, schools will be destroyed," calling the decision, "fallacious and maybe even disingenuous."

Since his inauguration in January, Trump has not approved any additional military aid packages for Ukraine. Defense Secretary Pete Hegseth also announced recently that the U.S. will reduce the total aid it sends to Ukraine in its upcoming defense budget.

In his evening address on July 2, President Volodymyr Zelensky said Ukrainian and U.S. officials are working through the aid issue at a "working level," including discussions on critical air defense support. Head of the Presidential Office Andriy Yermak held a late night phone call with Rep. Brian Mast, Chair of the House Committee on Foreign Affairs.

Ukraine's Defense Ministry said it has not received any formal notification of delays or cancellations but has requested urgent consultations with U.S. defense officials.

The Foreign Ministry also summoned U.S. Charge d'Affaires John Ginkel, warning that "any hesitation" in military support would encourage further Russian aggression.

The Kremlin welcomed the decision, with spokesperson Dmitry Peskov saying, "The fewer weapons that are supplied to Ukraine, the closer the end of the (war)."

NATO Secretary General Mark Rutte expressed understanding of Washington's desire to safeguard its stockpiles but said, "Ukraine cannot do without all the support it can get."

The U.S. Senate is postponing action on a bipartisan Russia sanctions bill until at least July, as other legislative and foreign policy priorities dominate the agenda, Semafor reported on June 18.

Senators Lindsey Graham (R-S.C.) and Richard Blumenthal (D-Conn.) have been working on a revised version of their bill that would impose secondary sanctions on Russian trading partners, while shielding Ukraine’s allies from penalties and making technical adjustments. But momentum has stalled as Republicans push President Donald Trump’s sweeping tax and spending bill, and the escalating conflict between Iran and Israel demands urgent attention.

Senate Majority Leader John Thune (R-S.D.) acknowledged on June 18 that a "July timeframe" was now more realistic for the sanctions bill. "We’re very open to moving, we’re trying to work with the administration from a timing standpoint," Thune said, according to Semafor. Graham added that the Senate is "going to have to wait a bit," citing shifting global developments. "Things are changing now with Iran… that doesn’t mean I’ve forgotten about Russia or Ukraine. Not at all. Iran is center stage, but sooner rather than later," he said.

Trump has not yet signaled support for the legislation, which remains a critical obstacle.

While sanctions enjoy broader Republican backing than direct military aid to Ukraine, GOP lawmakers are hesitant to move forward without Trump’s approval. The U.S. president left the G7 summit in Canada early, skipping a planned meeting with President Volodymyr Zelensky, as attention shifted to a potential U.S. response to Iran’s nuclear ambitions. "All the focus is on Israel and Iran right now," said Sen. Tommy Tuberville (R-Ala.), though he noted that he is "all for putting sanctions" on Russia.

Graham and Blumenthal had hoped to secure passage of the bill ahead of the G7 summit after visiting Ukraine earlier this year. Blumenthal said he and Graham were "making tremendous progress" with the administration, but acknowledged that other priorities were pushing the legislation off the floor.

Supporters of the sanctions argue the bill would give Trump more leverage in negotiations with Russian President Vladimir Putin. "We want to strengthen our hand in the negotiation," said Sen. John Hoeven (R-N.D.). "We want to help effectuate an outcome in Ukraine, so we’re trying to use it in a way that actually helps get something done." The legislation would authorize secondary sanctions on countries that continue to purchase Russian energy or conduct other major trade with Moscow.

Despite uncertainty around timing, both Graham and Blumenthal continue to refine the bill to ensure broader support, including a carveout for Ukraine’s allies and changes to accommodate the global banking system. "There is no evidence that Putin is going to slow down," Graham told Semafor. "We need to change the approach. I think the sanctions will give the president leverage."

“I said, Vladimir, let’s mediate Russia first. You can worry about this later,” U.S. President Donald Trump said.
