WASHINGTON — President Donald Trump's administration asked the U.S. Congress on Wednesday for $87.6 billion in additional funding, most of it related to the Iran war, setting the stage for another fight with lawmakers already frustrated with the conflict.

The supplemental funding request, posted on the White House website and transmitted to Congress, includes $67.15 billion for the military, in addition to some $1 trillion appropriated last year and another $1.5 trillion Trump wants for next year.

The White House said the latest funding request is to cover operational costs of the Iran war, including for military personnel and readiness, operational costs to rebuild weapons stocks, and classified programs.

The funding request for the military includes $21 billion to procure munitions, strengthen the U.S. industrial base and support critical capabilities.
