JD started it.

9. Yup, JD jumped in when Trump was wrapping up and asking for the last question.

“The path to peace and the path to prosperity is maybe engaging in diplomacy,” Vance said after pre-empting Trump’s attempt to field one last inquiry from the media. “We tried the pathway of Joe Biden, of thumping our chest and pretending that the president of the United States’ words mattered more than the president of the United States’ actions. What makes America a good country is America engaging in diplomacy. That’s what President Trump is doing.”

Zelenskyy then asked for and received permission to address Vance directly, noting that Ukraine had previously made diplomatic agreements with Russia that were then violated.

“He killed our people, and he didn’t exchange prisoners,” a visibly agitated Zelenskyy said, referring to Putin, who has been at war with Ukraine for three years. “What kind of diplomacy, JD, you are speaking about? What do you mean?”

Vance shot back that it was "disrespectful" for Zelenskyy to "come to the Oval Office to try to litigate this in front of the American media." Things only got more tense from there.
