The recent escalation will likely rekindle the debate over whether Trump has the power to battle Iran without Congress’ consent

Last year, months before the United States killed a senior Iranian commander in a dramatic escalation of tensions in the Middle East, bipartisan majorities in both the House and Senate voted to limit President Donald Trump’s ability to go to war with Iran.
The language never actually made it into law, marking another defeat for lawmakers in both parties who have clamored to reassert Congress’ constitutional authority to declare war since the sweeping war authorizations of 2001 and 2002 that have been used to justify American military incursions since then.
