WASHINGTON, May 12 (Reuters) – The United States’ war in Iran has cost $29 billion so far, a senior Pentagon ​official said on Tuesday, an ‌increase of $4 billion from an estimate provided late last month.

With just six months before midterm elections in which President Donald Trump’s Republicans may ‌face ​an uphill battle to ⁠keep their House ⁠majority, Democrats are riding high in public opinion polls as they attempt to link the war with cost of ​living issues.

On April 29, the Pentagon said the war at that point ⁠had cost $25 billion.

Jules Hurst, ⁠who is performing the duties ​of the comptroller, told lawmakers on Tuesday ​that the new cost included updated ‌repair and replacement of equipment and operational costs.

“The joint staff team and the comptroller team are constantly looking at ⁠that estimate,” Hurst said. He was speaking alongside Defense Secretary Pete Hegseth and Chairman of Joint ⁠Chiefs ‌of Staff, General Dan Caine.

It ⁠is unclear how the Pentagon ​arrived ‌at the $29 billion figure. A ​source told ⁠Reuters in March that Trump’s administration estimated the first six days of the war had cost at least $11.3 billion.
