June 18 (Reuters) - The U.S. Department of Defense needs $80 billion to cover costs from the Iran war as well ‌as other non-war-related bills, Deputy Defense Secretary Stephen Feinberg ‌told lawmakers in phone calls this week, the Wall Street Journal reported on ​Thursday, citing people familiar with the matter.

A full U.S. supplemental request, which will include money for the Pentagon as well as non-defense priorities such as farm and disaster relief, could be sent to ‌lawmakers in the coming ⁠days, the newspaper added.

Reuters could not immediately verify the report. The White House and Pentagon were not ⁠immediately available for comment outside business hours when contacted by Reuters.

The Iran war has cost around $25 billion, a Pentagon official told Reuters in ​April ​providing the first official estimate of ​war costs.

However, the full ‌cost of the conflict, which Trump began alongside Israel on February 28, has remained an open question on Capitol Hill and an initial $200 billion request for additional funding met stiff opposition from lawmakers.

White House budget director Russell Vought told a hearing in April of ‌the House of Representatives Budget Committee that ​he had no estimate for the ​cost of the war, ​as he defended Trump's request for a $1.5 trillion ‌annual military budget.

The proposed budget reflects ​Republican priorities ahead ​of November’s midterm elections, where the party is trying to keep control of Congress but is facing growing voter anxiety ​over rising living ‌costs, high energy prices and the financial burden of ​the Iran war.
