Republican Sen. J.D. Vance of Ohio ripped into the Biden administration for tunnel vision in terms of national security.

In a Thursday post on X, Vance lashed out after learning the administration was putting Ukraine at the front of the line for all new Patriot missile deliveries.

"At this point we are actively endangering our national security by focusing on Ukraine to the exclusion of other priorities. A slow running disaster from the Biden admin," he said.

White House spokesman John Kirby said Thursday that the administration made a "difficult but necessary decision" as Ukraine's infrastructure takes a pounding from Russia, according to The New York Times.

"The broader message here to Russia is clear," Kirby said. "If you think you're going to be able to outlast Ukraine, and if you think you're going to be able to outlast those of us who are supporting Ukraine, you're just flat-out wrong."

He said National Advanced Surface-to-Air Missile Systems also would be prioritized for Ukraine, according to The Washington Post.

Kirby said neither Taiwan nor Israel would be impacted by the policy shift.

Last week, President Joe Biden said that other nations agreed to send Patriot missiles and other air defense assets to Ukraine and that other countries would need to wait because "everything we have is going to go to Ukraine until their needs are met, according to the Financial Times, which first reported the change in policy.

Biden said the change in prioritizing deliveries would come "relatively quickly."

The Financial Times reported that Romania would donate a Patriot system to Ukraine, while Spain and Greece have not done so. Poland has said its Patriot batteries are already guarding Ukraine's supply lifeline.
