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.

Some Senate lawmakers, both Democrats and some Republicans, questioned the need for the money on top of the defense request and the roughly $150 billion in additional funding the military received through Trump’s so-called Big Beautiful Bill.

Sen. Patty Murray, D-Wash., the committee’s top Democrat, said the request for emergency funds “may be better understood as an attempt toskirt the normal appropriations process.”

“The problem is not a lack of money, but poor planning,”Murray said. “So I’ll be blunt. The truth is, your request does not make a lotof sense.”

Hegseth, in response, blamed “gross negligence and neglect”by the Biden administration.

Some asked about Iran’s military capabilities and theobjectives of the war, as Hegseth and Trump have both previously said that the war had been won. The defense secretary also said in the early days of the war that Iran’s military had already been “destroyed and made combat-ineffective.”

Hegseth said that he never meant that Iran would be unable to launch any attack. He said he meant Iran “can lob missiles, but it’s not an effective military.”

Sen. Lisa Murkowski, R-Ala., asked Hegseth if the Trump administration believes it does not need authorization from Congress to continue the war. Hegseth replied that the administration believes it already has the authority it needs.

The hearing lasted more than three hours and ended in a shouting match between Hegseth and Sen. Gary Peters, D-Mich., who questioned the war’s objectives, called Hegseth a “failure” and said the Trump administration has created another “forever war.”

Hegseth responded by telling Peters “shame on you” and saying he has “Trump derangement syndrome.”
