US war in Iran has cost $37.5 billion so far, Pentagon says

WASHINGTON, July 21 (Reuters) - The United States' war in Iran has cost $37.5 billion so far, U.S. Defense Secretary Pete Hegseth said on Tuesday, an increase of nearly $8 billion since the last public estimate.

Hegseth told lawmakers that the figure also included anticipated costs through September 30.

This is the first time that Hegseth, who appeared before the Senate Appropriations Committee along with Chairman of the Joint Chiefs of Staff General Dan Caine, has publicly faced questions from lawmakers since the U.S. military re-started operations against Iran earlier this month.
