Biden’s speech in Arizona was interrupted by the climate activist Kai Newkirk, who called on the president to declare a climate emergency.

Kai Newkirk: “Please excuse my interruption, Mr. President, but I’m compelled by conscience to ask why you have yet to declare a climate emergency. Why have you yet to declare a climate emergency? Hundreds of Arizonans have died.”

President Joe Biden: “I tell you what: If you shush up, I’ll meet with you immediately after this. OK?”
