July 21 (UPI) -- U.S. Secretary of Defense Pete Hegseth told a Senate committee Tuesday that the financial cost of the Iran war has now reached about $37.5 billion according to Defense Department estimates.

Lawmakers questioned Hegseth and Joint Chiefs of Staff Chair Gen. Dan Caine during a Senate Appropriations Committee meeting as the Pentagon and President Donald Trump are seeking up to $70 billion in emergency military funds.

This is in addition to the $1.5 trillion the Pentagon has requested in the upcoming defense budget. Trump has also asked for about $18 billion more in emergency funds for unrelated programs, including $11 billion for agriculture. Agriculture Secretary Brooke Rollins was also present at the hearing, although the focus remained on military spending.
