Florida Gov. Ron DeSantis, responding to the surprise news that President Joe Biden had arrived in Kyiv, downplayed Russia’s military threat to greater Europe on Monday as “third-rate” and criticized the administration’s aid to Ukraine as a “blank-check policy.”

“The fear of Russia going into NATO countries and all that and steamrolling, you know, that has not even come close to happening,” the Republican governor said on Fox’s “Fox & Friends,” appearing from New York. “I think they’ve shown themselves to be a third-rate military power.”

The U.S. has determined Russia is committing crimes against humanity in Ukraine, Vice President Kamala Harris announced on Saturday, a year into the largest ground war in Europe since World War II.

DeSantis, who is considered a likely candidate for the Republican presidential nomination next year, criticized Biden and his administration for visiting Ukraine instead of focusing on other priorities.

“He’s very concerned about those borders halfway around the world. He’s not done anything to secure our own border here at home,” DeSantis said, referring to the southern border.

Rep. David Kustoff (R-Tenn.), while giving “kudos” to Biden for visiting Ukraine, suggested the president should have instead visited the site of this month’s toxic train derailment in East Palestine, Ohio.

“There are a lot of people here in the U.S. that would say he probably should have gone to Ohio and visited with the people who have been afflicted by the derailment first,” Kustoff said on Fox Business, also criticizing the amount of spending on aid to Ukraine.

Biden visited Kyiv on Monday morning to show solidarity, a surprise appearance marking the anniversary since Russia invaded on Feb. 24, 2022. In an address with Ukrainian President Volodymyr Zelenskyy, Biden also announced a new half-billion-dollar weapons package to Ukraine.

The administration has “no clear strategic objective identified” as it provides aid, DeSantis said.

“And I don’t think it’s in our interest to be getting into proxy war with China, getting involved over things like the borderlands or over Crimea,” he said. While Russia is “hostile,” he said, China poses a bigger threat.

The Biden administration has repeatedly disputed the idea that it is providing blank checks to Ukraine.

“There’s been no blank checks,” National Security Council spokesperson John Kirby said this week on Fox’s “Fox News Sunday.” “Every single item that we have sent in to Ukraine has been done in full consultation with the Congress.”
