The War Powers Resolution, enacted after the Vietnam War, is gaining attention as Donald Trump's military actions in Iran approach a critical deadline. Under this law, the president must notify Congress within 48 hours of deploying troops and seek approval within 60 days. If Congress does not approve, military involvement must end. The exact deadline for Trump's actions is debated, with estimates ranging from late April to May 1. Some lawmakers argue the 60-day clock began with the start of hostilities, while others believe it started upon formal notification to Congress. A ceasefire has further complicated the timeline, with some suggesting it could reset the clock. Despite the law's framework, it has rarely been enforced, and previous presidents have found ways to circumvent its limits. As the deadline approaches, divisions in Congress make consensus difficult, highlighting the ongoing tension between presidential authority and congressional oversight.
