Ukrainian President Volodymyr Zelenskyy’s address to Congress on Wednesday night received multiple standing ovations and praise from lawmakers on both sides of the aisle.

But not from everyone.

A small but vocal group of Republicans have blasted not only the idea of allocating more funding for Ukraine to help in its war against Russia but also showing adulation to Zelenskyy.

In his speech, Zelenskyy, traveling outside Ukraine for the first time since Russia invaded his country in February, thanked the United States for tens of billions of dollars in U.S. military and economic assistance provided over the past year, and he appealed for more.

“Your money is not charity,” he said. “It’s an investment in the global security and democracy that we handle in the most responsible way.”

Reps. Lauren Boebert of Colorado, Andrew Clyde of Georgia, Matt Gaetz of Florida and Jim Jordan of Ohio were among those Republicans who remained seated as others around them stood to applaud Zelenskyy's remarks. Sen. Josh Hawley of Missouri and Rep. Thomas Massie of Kentucky skipped the speech entirely. And other conservatives have criticized the Ukrainian leader’s speech.

“I didn’t go to the speech because I didn’t want to be part of a photo op asking for more money from the United States government when they have not given us a single piece of accounting on anything they spent,” Hawley told reporters Thursday.

Massie tweeted before the speech: "I’m in DC but I will not be attending the speech of the Ukrainian lobbyist."

In an interview with Fox News’ Tucker Carlson on Thursday night, Gaetz, too, raised concerns about oversight of U.S. funding for Ukraine.

“I feel no compunction to go out and applaud some foreign leader from a historically corrupt country who is begging for more than the $100 billion that the Congress has already set to send them,” Gaetz said.

Gaetz criticized the $1.7 trillion government funding bill passed by the Senate on Friday and the House on Thursday, which includes about $45 billion more in Ukrainian aid.

“Washington actually thinks that they should go to great lengths to keep Ukraine whole while at the same time funding the balkanization and division within our own country,” Gaetz said. “And I'm not sorry that Lauren Boebert and I won't stand for it.”

Gaetz called the speech “some sort of North Korea-style performance.”

Carlson has been especially critical of Zelenskyy and the reception he received in Washington. The Fox News host on Thursday introduced Gaetz as “one of the very few members of Congress … who didn't follow the rules and stand up and applaud like a seal as a foreign leader in a sweatshirt lectured our country.”

Carlson also called the democratically elected Zelenskyy a “foreign dictator” and an “uppity foreigner.” A night earlier, he said the Ukrainian president was “dressed like the manager of a strip club."

Boebert said in a Twitter video immediately after the speech: "Sadly, what I didn't hear tonight was a clear explanation of where the first $50 billion we sent to support their efforts went." 

Rep. Paul Gosar, R-Ariz., tweeted after Zelenskyy’s speech that the U.S. “should not fund this war. We have no interest to defend in Ukraine.”

“A true leader would be seeking peace,” he said.

Several Republicans have been calling for greater scrutiny of the U.S. expenditures in Ukraine. 

In October, House Minority Leader Kevin McCarthy, R-Calif., said Republicans would not write a “blank check” for Ukraine if they won control of the House in the midterm elections, which they did a few weeks later. McCarthy walked back the comments, saying he supported aid for Ukraine but wanted more oversight of the money.

Rep. Marjorie Taylor Greene, R-Ga., introduced a resolution last month to audit the the U.S. military and economic aid for Ukraine, which gained traction within her party but failed to clear the Democratic-led Foreign Affairs Committee. The measure would instantly have better odds of passing if reintroduced in the GOP-led House next year.

There are, however, already steps in place aimed at ensuring the money is not misused. Sen. Rob Portman, R-Ohio, noted in a speech this week that the World Bank regularly provides reports and audits of the funding. The Pentagon and State Department inspectors general have said they, too, are conducting audits on Ukraine aid.

The government funding bill approved by Congress this week also includes several provisions aimed at ensuring closer oversight of the spending.

To be sure, many Republican lawmakers have backed continued financial support for Ukraine and have complimented Zelenskyy.

For example, Sen. Lindsey Graham of South Carolina said Zelenskyy “delivered one of the most inspiring speeches to a joint session of Congress I have ever witnessed.”

Graham this week introduced an amendment to the $1.7 trillion omnibus spending bill that would allow the U.S. to transfer assets seized from Russian oligarchs to Ukraine as aid. The measure was adopted into the spending bill, which the House sent to President Joe Biden's desk on Friday.

Likewise, Portman called Zelenskyy’s address “an inspiring call to action for America.”

Senate Minority Leader Mitch McConnell, R-Ky., said providing assistance to Ukraine the “No. 1 priority for the United States right now.”

That comment was met with backlash from some conservatives, including Gosar.

“I have news for @LeaderMcConnell: America has 99 problems but the Ukraine ain’t one,” Gosar tweeted.
