Trump’s May 1 deadline: Can he continue war on Iran after that?

The US President is required to limit deployments in any ongoing conflict after 60 days under the War Powers Resolution, unless granted specific authorisation to continue. To grant this, both the House of Representatives and the Senate must pass a joint resolution within the 60-day limit. The President must inform Congress within 48 hours of initiating military action and may sustain deployments for only 60 days, unless extended by Congress.
