President Donald Trump took the United States to war without a vote of support from Congress, but lawmakers are increasingly questioning when, how and at what cost the war with Iran will come to an end.

Multiple countries are offering assistance but not on the scale that the White House wants.

The first six days of Donald Trump’s war against Iran cost a whopping $11.3 billion, according to a report from the Pentagon given to Congress earlier this month. The pricetag is expected to continue climbing — exponentially.

Donald Trump's war with Iran is weighing on independent US voters, a crucial bloc likely to determine if the president's Republican Party maintains control of Congress in the November midterm elections.

GOP fiscal hawks warn that a potential $200 billion funding request for the Iran campaign must be offset by spending cuts as the national debt surpasses a staggering $39 trillion.

President Donald Trump is reportedly gearing up to ask Congress for a massive cash infusion for war in Iran at a time when his administration has made controversial cuts to other marquee government programs and left others unfunded and his tax cuts add to the federal deficit.

Democrats and some Republicans are alarmed by the Trump administration's pursuit of another $200 billion for the war against Iran, with some saying it signals a dangerous escalation of the conflict and highlights a lack of coherent strategy.

A Republican congressman has a solution to the Pentagon’s $200 billion price tag for the Iran war: send the bill to the country America is bombing. Pennsylvania Rep. Scott Perry appeared on CNN on Thursday after the Department of Defense requested supplemental funds to keep President Donald Trump’s war on Iran going.
