What was the contentious exchange between Anderson Cooper and Chris Sununu about on CNN?

The clip describes a tense on-air moment where CNN's Anderson Cooper became visibly upset with New Hampshire Governor Chris Sununu over a discussion about cuts proposed by Elon Musk. Cooper apparently called out Sununu during their exchange, creating an awkward broadcast moment. The commentator points out the irony of this confrontation given that Sununu was sharing the screen with Jeffrey Toobin, who is primarily known for his own controversial on-air incident. This interaction illustrates the heightened tensions in political media coverage surrounding Musk's influence on potential government cuts.
