Former Representative Marjorie Taylor Greene (R-Ga.) criticized President Trump's recent threat against Iran during a CNN interview Thursday, calling his remarks "absolute madness."

Greene was responding to Trump's statement earlier this week in which he warned that Iran's "whole civilization will die" if the country took action against the United States. The threat was posted on Trump's social media platform.

During the interview with CNN's Pamela Brown and Wolf Blitzer, Greene described Trump's Iran statement as "the final straw" for her. When asked to explain her opposition to the president's remarks, Greene emphasized the severity of her concerns about the threatening language.

The criticism from Greene, a former Trump ally who previously supported many of his policies, represents a notable break from the president on foreign policy matters. Greene served in Congress as a Republican representative from Georgia before losing her seat.

Trump's Iran threat came amid ongoing tensions between the United States and Iran, though the specific context that prompted his social media post was not detailed in the available reports.
