The White House Office of Management and Budget sent the formal request for the funds on Wednesday in a letter to House of Representatives Speaker Mike Johnson.
“Most of this request will address urgent needs related to Operation Epic Fury (OEF),” says the letter, referring to the Iran war.
The request includes $21bn for munitions, $17.3bn for operational costs and $12.1bn for classified programmes. It also asks for about $300m to bolster security at US embassies and diplomatic outposts in the Middle East and South Asia after some of them came under attack earlier in the war.
The other requested money would be for unrelated measures, including $11bn for US farmers and $1.4bn to tackle the Ebola outbreak in Central Africa.
Washington and Tehran are currently observing a ceasefire in the war, but the White House budget office letter notes that the Pentagon needs to “rebuild stocks” after its military strikes.
A peace plan was last week agreed between Trump and Iran, but dissident voices within the Republican Party have voiced scepticism about it.
The meeting between the president and senators on Wednesday was said to have been tense after Trump abruptly called off a signing ceremony for a housing bill that had bipartisan support.
At the lunch on Capitol Hill, Trump went on to complain about the measure that was passed the previous evening, when the Republican-controlled Senate narrowly voted to call for a restriction on his war powers.
Despite being largely symbolic, the measure was the first resolution of its kind to clear Congress that demanded a president to end a military action.
Early on Wednesday, Trump described it as “poorly timed and meaningless”. On social media, he branded the four Republican senators who sided with opposition Democrats as “losers”. And in a meeting with Nato chief Mark Rutte, Trump said the group “want to lose the war because they’re stupid.”
Later, after the closed-door lunch, Cassidy gave journalists an account of what he alleged had been a shouting match with the president: “I stood and said, ‘You have not told the American people what’s going on.'”
Cassidy went on to say: “This was supposed to last four weeks, it’s lasted four months. Our original objectives have not been achieved.”
For his part, Trump told reporters: “I think we had a really great meeting.”
But by the end of Wednesday, Cassidy’s concerns appeared to have been assuaged, writing on X that he had received a “thorough briefing” from Vice-President JD Vance and Steve Witkoff, Trump’s special envoy.
Later that day, the senator changed his vote to help defeat another war powers resolution in the Senate – a move that was welcomed by Trump.
Last month, the Pentagon’s chief financial officer Jules Hurst told a congressional panel the war had cost about $29bn so far.
But defence analysts and lawmakers say this estimate does not reflect the full scale of the conflict’s financial damage.
