I found another clip which starts a minute earlier. Based on this clip, it seems the meeting was progressing better then well until the VP started talking.
Vice President tried to impress President Trump by mentioning unnecessary points. Meanwhile, President Zelenski lost his temper, which was unprofessional. In high-stakes diplomacy, one must maintain composure.
The Vice President may become a liability for President Trump. The VP seeks endorsement to carry Trump’s legacy in 2028, but during the Fox News Super Bowl interview, President Trump hinted at a different candidate, likely one of his children. It is not unusual, as the U.S. has had father-son presidents before. This is within President Trump's prerogative. I assume the Vice President will attempt to persuade President Trump and demonstrate that he is the rightful candidate to continue Trump's legacy.
