Conservative commentator Megyn Kelly pressed Vice President JD Vance on the growing split within the Republican Party over the Trump administration’s military operation in Iran.Kelly described the relationships within the party as a “civil war,” saying that, as a right-leaning independent, she would rather argue with Democrats than Republicans. She said Republicans who disagree with President Donald Trump’s Iran war feel “betrayed” and gave Vance an opportunity to respond to those critics. “Even if you disagree with this particular action, it’s completely ridiculous to pick up your marbles and go home,” Vance said on The Megyn Kelly Show Tuesday. “That’s not how politics works.”

Vance elaborated on this point, saying he’s been listening to the debates and conversations about the administration’s policies on a variety of issues, including immigration, taxes, and foreign affairs.

“I’ve been very much on the inside on a lot of these debates and conversations,” Vance said. “The way that politics works is that you have to stay engaged in the process. You absolutely have to make your voice heard, but right now, right now we have a very good deal for the American people.”

Trump announced on Saturday that the United States reached a peace deal with Iran. Vance confirmed in an interview with ABC News on Monday that the deal was “already signed” digitally, as the vice president will represent the U.S. at the formal signing in Geneva on Friday.
