What was supposed to be a typical bilateral White House meeting followed by the signing of a mineral rights deal between President Donald Trump and Ukrainian President Volodymyr Zelensky on Friday devolved into an acrimonious confrontation between the two leaders that was broadcast for the world to see.

Now some top Republicans in Congress, including some who have strongly supported Zelensky as he leads Ukraine's defense against a Russian invasion, are calling for the Ukrainian president to resign, according to Fox News.

That includes Sen. Lindsey Graham (R-SC), among the most hawkish and pro-Ukraine GOPers on Capitol Hill, who suggested to reporters that Zelensky can no longer be trusted for the U.S. to continue doing business with.

Graham says Zelensky "needs to resign" or "needs to change" his attitude

Sen. Graham was a spectator in the Oval Office during the contentious meeting between President Trump, Vice President JD Vance, and President Zelensky, and the senator told reporters afterward that the meeting had been a "complete and utter disaster."

"Somebody asked me, am I embarrassed about Trump?" Graham said. "I have never been more proud of the president. I was very proud of JD Vance standing up for our country."

"We want to be helpful -- what I saw in the Oval Office was disrespectful and I don't know if we can ever do business with Zelensky again," he continued.

"The way he handled the meeting, the way he confronted the president was just over the top," Graham added of Zelensky, per Fox News. "He either needs to resign and send somebody over that we can do business with, or he needs to change."

Johnson said perhaps "someone else needs to lead the country"

Sen. Graham was not alone in suggesting that it was time for President Zelensky to step aside, as NBC News reported that House Speaker Mike Johnson (R-LA) said much the same thing during a Sunday morning appearance on "Meet the Press."

The speaker called out Zelensky for having "berated and interrupted his host," President Trump, "instead of expressing gratitude for the extraordinary help that the U.S. has provided his country."

Johnson said the Ukrainian leader "needs to come to his senses and come back to the table in gratitude or someone else needs to lead the country, and further noted of Ukraine and Russia, "President Trump is trying to get these two parties to a point of peace."

"What President Zelenskyy did in the White House was effectively signal to us that he’s not ready for that yet, and I think that’s a great disappointment," he added and pointed out that Trump "has been very clear about this -- that if [Zelenskyy] is ready for peace, then we can negotiate a deal."

Unknown if Zelensky is prepared to "negotiate in good faith"

Axios reported that White House National Security Adviser Mike Waltz didn't explicity call for President Zelensky to resign but nonetheless seemed to suggest an openness to the idea, contingent upon whether Zelensky was ready to accept the terms of a deal to end the fighting.

During an appearance Sunday on CNN's "State of the Union," Waltz revealed that it was entirely unclear to the Trump administration if Zelensky was truly "ready to negotiate in good faith."

As for the suggestions that Zelensky should resign, Waltz said that "if it becomes apparent that President Zelensky's either personal motivations or political motivations are divergent from ending the fighting in his country, then ... I think we have a real issue on our hands."
