Hey from CNN, I'm Ifeoma Dike with the five things you need to know for Monday, May 4th.

'A ceasefire between the US and Iran is in question as tensions escalate in the Strait of Hormuz. US officials are trying to reopen the critical waterway through a mission dubbed Project Freedom. US Central Command says it'll feature more than 100 land and sea-based aircraft and 15,000 service members. However, a US official says this isn't an escort mission. Iran argues that Project Freedom violates the ceasefire and appeared to respond by resuming attacks in the region. Centcom says the US Military blew up six Iranian boats after Tehran launched multiple cruise missiles, drones and small boats at US Navy ships and commercial ships. In a phone interview with Fox News, President Donald Trump warned Iranian forces that they would be quote, blown off the face of the earth if they attempted to target US ships in the Region. CNN's Nic Robertson is in Pakistan.

When I met with Iranian officials here late Friday, they said, look, if we come to some agreement over the Strait of Hormuz What's the stop? Who's going to guarantee for us that the U.S. Navy doesn't move in and doesn't take control of the Strait of Hormuz? And this appears to be what the Iranians have responded to today. They said they would respond. They said that they would, uh, respond militarily. They've escalated it now to targeting not only the UAE, injuring three Indian nationals there, but targeting Oman as well, injurying two people there in a strike.

When we come back, the latest in the fight over access to an abortion pill.

'The Supreme Court has temporarily restored access to abortion pill Mifepristone by mail and telehealth. Danco Laboratories, the maker of Mifipristone, challenged an appeals court ruling on Friday that reinstated a nationwide requirement that the pill be obtained in person. The drug maker said the ruling caused immediate confusion to time-sensitive medical decisions. That appeals court rulings stemmed from a lawsuit filed by Louisiana last year against the FDA's rule allowing women to obtain abortion drugs by mail. Louisiana alleged the ruling undermined its own abortion ban and demanded that the FDA complete a safety review for the drug. CNN analysis shows Mifepristone is overwhelmingly safe and has fewer reported side effects than Viagra or penicillin. The Supreme Court's ruling today is far from final. Justice Samuel Alito said the decision would remain on hold until at least May 11th.

'Blake Lively and Justin Baldoni's production company have reached a settlement two weeks before trial. Details of the settlement were not immediately available. But this comes after a federal judge tossed out 10 of 13 claims in Lively's complaint, including sexual harassment and defamation. Lively accused Valdoni, who co-starred in the film It Ends With Us, of sexually harassing her during filming and then orchestrating a smear campaign to retaliate against her for speaking up. Valdone denied the allegations. Some of the claims were tossed due to legal technicalities, such as Lively being considered an independent contractor rather than an employee. The remaining three claims, retaliation, aiding and abetting retaliation and breach of contract, were not against Baldoni personally, but against his production company and a public relations company retained by his team. In a statement, Lively's legal team and the remaining defendants say, quote, It is our sincere hope that this brings closure and allows all involved to move forward constructively and in peace, including a respectful environment online.

Elon Musk wanted to settle with OpenAI two days before his massive trial against Sam Altman's AI company began last week. That's according to a new court filing from OpenAI. CNN's Hadas Gold reports.

'In this filing, OpenAI says Musk sent the message to OpenAI President Greg Brockman to gage an interest in a settlement. Brockman responded by suggesting all sides drop their respective claims, and then Musk shot back, saying, quote, by the end of this week, you and Sam, referring to Sam Altman, CEO of OpenAI, will be the most hated men in America if you insist, so it will be. Elon Musk brought this lawsuit because he has accused OpenAI and its leaders of reaching a charitable trust and unjustly enriching themselves. Musk, who helped fund and found OpenAI, says he was deceived after OpenAI went from a pure nonprofit to its current structure, where it's a for-profit public benefit corporation overseen by a nonprofit foundation. OpenAI has said Musk himself wanted a for profit element to the company and has only filed this lawsuit to go after what is now a competitor to his own AI company XAI. But the judge denied OpenAI's request to submit those messages as evidence, telling the attorneys they should have submitted them last week during Elon Musk's testimony.

Coming up, we have an update about an iconic pop star's DUI case.

Britney Spears pleaded guilty to a lesser charge in her recent DUI case that will allow her to avoid jail time. She was accused of driving under the influence of alcohol and drugs in California. Spears didn't appear in Ventura County Court, but on her behalf, her lawyer agreed to plead to what's called a wet reckless. That allows her to be sentenced to a year of probation, a required DUI class and state mandated fines. After the hearing, the district attorney said that Spears had taken, quote, full responsibility. But he emphasized that DUI is a serious crime and said it was essential that she follow the requirements agreed to in court. That includes continued substance abuse treatment, weekly visits with a therapist, and monthly visits with the psychiatrist.

That is it for us. We're back tomorrow morning.
