What we covered here
• Failed resolution: The US Senate rejected a Democrat-pushed resolution Friday that aimed to rein in President Donald Trump’s ability to use military action against Iran without congressional approval.
• Negotiation efforts: Iran’s foreign minister said that if Trump wants a nuclear deal with Tehran, he should do away with his “unacceptable” tone toward the country’s supreme leader. Trump — who cast serious doubt on any diplomatic progress — said he would “absolutely” consider bombing Iranian nuclear sites again if he thought it necessary.
• Activity at Iran nuclear site: Satellite imagery captured Friday appears to show new activity at Iran’s Fordow nuclear facility, which is buried deep inside a mountain to guard it from attacks and was hit by Israeli and US airstrikes.
• Bunker-buster update: The US military did not use bunker-buster bombs on one of Iran’s largest nuclear facilities last weekend due to the site’s depth, the top US general told senators, according to sources.
