Longtime Ukraine advocate Sen. Lindsey Graham, R-S.C., fired shots back at Ukrainian President Volodymyr Zelenskyy, who suggested the U.S. lawmaker move to Ukraine, so his voice will have weight.

Graham shared a clip posted by Fox News host Laura Ingraham on Sunday showing Zelenskyy speaking with a reporter.

During the interview, Zelenskyy was asked about Graham, who said he should consider resigning as president of Ukraine.

“Lindsey Graham is a very good guy…I can give him Ukrainian citizenship, then his voice will gain weight,” Zelenskyy said.

“I have never been more proud of the president. I was very proud of JD Vance standing up for our country,” Graham said. 

He slammed the “disrespectful” Oval Office display from Zelenskyy, going as far as saying, “I don’t know if we can ever do business with Zelenskyy again.”

According to the senator, he doesn’t think Americans saw the Ukrainian president as someone they feel comfortable going “into business with” following the televised dispute.

Graham also stressed that the Ukrainian-American relationship is “vitally important.” However, he cast doubt on whether Zelenskyy could ever “do a deal with the United States.”
