The US Senate advanced a war authorization resolution that would prevent President Donald Trump from continuing military operations in the ongoing conflict with Iran without Congressional approval. This procedural vote, which passed 50 to 47, stands out as a rare congressional warning to Trump. The resolution is seen as a victory for lawmakers who argue that the constitutional power to declare war belongs to the legislative branch, not the president. However, for the resolution to become law, it must also pass the House of Representatives and overcome a likely veto from Trump. Democratic Senator Tim Kaine stated that this resolution is important to end the war with Iran and noted that Trump has not shared peace proposals with Congress. Trump's Republican supporters had previously blocked such measures. This development ignites new debates in the US about war powers and the president's role in military operations.
