Congress defeat: How Trump’s allies are distancing themselves from Iran war

What Happened

After Democrats won control of both chambers of Congress in Tuesday’s midterm elections, senior Republicans publicly distanced themselves from the US-Iran war launched in February alongside Israel. Vice President JD Vance wrote on X on Wednesday that “the reason we lost is the war,” said ending the Iran war and changing the US relationship with Israel were top reasons Trump 2024 voters switched to Democrats, and questioned whether losing the Senate for six years was worth it. Senator Ted Cruz called the conflict too long and said Washington should never give “the Ayatollah billions of dollars,” referencing a June memorandum of understanding between Washington and Tehran that included a $300bn fund to rebuild post-war Iran. President Donald Trump told reporters at the White House on Wednesday that Vance’s assessment was “largely true,” blaming higher fuel prices, but insisted the war was necessary to stop Iran from obtaining a nuclear weapon.

Why It Matters

The Republican infighting signals the Iran war is a domestic political liability, with 2028 aspirants such as Vance and Florida Governor Ron DeSantis positioning away from it. Paul Musgrave of Georgetown University in Qatar said the US decision to attack Iran triggered a global fuel crisis with the closure of the Strait of Hormuz, costing US taxpayers an estimated $47bn so far. Democrats controlling both chambers can use funding restrictions, hearings, and investigations to constrain the executive branch’s ability to continue combat operations, as seen in Representative Ro Khanna’s proposed continuing resolution to prohibit financing of US military combat activities in Iran.

Watch For

Monitor whether Congress advances Ro Khanna’s continuing resolution to prohibit funding for US combat activities in Iran, and whether the defence budget and debt limit extension become vehicles for bipartisan constraints. Watch for hearings or investigations led by newly empowered Democrats targeting Secretary of Defense Pete Hegseth and war planning. Also track whether Washington’s June memorandum of understanding with Tehran is revisited or replaced, and how Republican 2028 positioning by Vance, DeSantis, and Cruz evolves.
