Sen. Todd Young (R-IN) will oppose Sen. Tim Kaine’s (D-VA) war powers resolution blocking the U.S. from taking further military action against Iran, he revealed to Jewish Insider ahead of Friday’s vote.

The position is a shift for Young, who partnered with Kaine in early 2023 to successfully pass legislation repealing the 1991 and 2002 Authorizations of Military Force to formally end the Gulf and Iraq wars. The two introduced their first joint war powers repeal bill in 2019, and Young voted for an amended version of Kaine’s 2020 war powers resolution following President Donald Trump’s decision to assassinate Iranian Gen. Qassem Soleimani after initially opposing the Virginia Democrat’s original language. 

The Indiana senator, who has been a leader on the GOP side in efforts to update and enforce Congress’ war-making powers, told JI on Friday that he will vote no on Kaine’s latest resolution, citing his belief that Iran’s nuclear program was a direct threat to the U.S. meriting a targeted response. 

“Following recent briefings, I feel confident that Iran was prepared to pose a significant threat to the security of the United States and Israel, making the president’s decision to pursue limited, targeted action necessary and based on the appropriate legal foundation. America and the world are safer because of the skill and determination of our military personnel who acted last Saturday,” Young said in a statement.

Young also said that given President Donald Trump’s push for a ceasefire rather than an escalation of U.S. military action in Iran, he did not view the resolution as needed. Still, he cautioned that the Trump administration should engage with Congress on any future military actions.

“Based on President Trump’s stated goal of no further military action against Iran and conversations with senior national security officials regarding the administration’s future intentions, I do not believe this resolution is necessary at this time,” Young said.

“Should the administration’s posture change or events dictate the consideration of additional American military action, Congress should be consulted so we can best support those efforts and weigh in on behalf of our constituents. I am prepared to work with the Trump administration to advance a targeted authorization for the use of military force against Iran should the situation require it,” he continued. 

Sen. Ted Cruz (R-TX) on Tuesday proposed an amendment to Sen. Tim Kaine’s (D-VA) war powers resolution, which would block the U.S. from taking further military action against Iran, commending President Donald Trump for a “successful mission” in damaging the regime’s nuclear program. 

Cruz introduced the amendment in anticipation of a vote later this week on the resolution, which would curtail the president’s ability to take any additional action targeting Iran without congressional approval. The amendment, if adopted, would attach language to the resolution celebrating the very actions it seeks to block.

“Members of the United States Armed Forces and intelligence community, and all those involved in the planning and successful execution of Operation Midnight Hammer on June 21, 2025, including President Donald J. Trump, should be commended for their efforts in a successful mission,” the amendment reads.

The Texas senator offered an identical amendment praising the president’s actions when Kaine introduced a war powers act in 2020 in response to Trump’s decision to assassinate Quds Force head Gen. Qassem Soleimani. That amendment, which said that those involved in the operation “should be commended for their efforts in a successful mission,” passed 64-34. 

“The Senate routinely passes this language to applaud presidents for operations like these, which make all Americans immeasurably safer. We came together to congratulate President Obama for liquidating Osama bin Laden, and the Senate voted to applaud President Trump for doing the same to Soleimani. I intend to ensure we do the same for this weekend’s crucial operation, which eliminated the existential threat to America of a nuclear-armed Iran,” Cruz told Jewish Insider in a statement. 

Kaine told reporters on Monday that his resolution was likely to come up for a vote on Thursday or Friday.
