BALDWIN: For almost 50 years, access to abortion has been protected by Roe v. Wade, but now the court is looking at abortion law again. This time, with a strong 5-4 conservative majority. This Louisiana law under consideration requires abortion providers to have admitting privileges at nearby hospitals, but the case could signal how willing the more conservative court is to roll back abortion rights. So this is the first major abortion case that will be heard by President Trump's two nominees, Neil Gorsuch and Brett Kavanaugh. CNN's Supreme Court Reporter, Ariane De Vogue is with me now. What happened today, Ariane?</s>ARIANE DE VOGUE, CNN SUPREME COURT REPORTER: Brooke, they seemed divided in court. It seemed like Chief Justice Roberts and Brett Kavanaugh might be receptive to upholding this law. But really, Chief Justice John Roberts is going to be key here. It was too hard to tell at oral arguments where he's going to come out. Keep in mind, this is one of the most explosive cases of the term here. Supporters of abortion rights think this new court is about to gut court precedent. They're very worried. Louisiana says, look, this law is necessary for public safety. Critics say that there's no reason for the law, that abortion is a very safe procedure. And in court, Brooke, Justice Ruth Bader Ginsburg was really fiercely on their side. But the most important thing to remember is it was just four years ago when the Supreme Court struck down a similar Texas law. So all eyes are going to be on Chief Justice John Roberts to see just how much this court has now changed four years later -- Brooke?</s>BALDWIN: We'll see how they go. I know a lot of people are in front of that court today with differing opinions on the issue. Ariane De Vogue, thank you, in Washington. We are just moments away from Mike Bloomberg's address to supporters and staff. Hear why he is now throwing his support behind Joe Biden.
