BALDWIN: Major legal battle today before the United States Supreme Court. Justices heard oral arguments in a case that could keep about four million undocumented immigrants from being deported. Protesters on both sides of the issues rallied outside the courthouse today there in Washington, while inside, lawyers made their case on whether executive actions taken by President Obama two years ago are, in fact, constitutional. CNN's justice correspondent, Pamela Brown, is in Washington following all the developments for us. What happened today, Pamela?</s>PAMELA BROWN, CNN JUSTICE CORRESPONDENT: You know, Brooke, this is a case that not impacts millions of people in the United States, but it has broad implications for the relationship between the president and Congress. And during the 90 minutes of oral arguments, it was intense. You could feel how high the stakes are and the justices seemed divided along ideological lines as they grappled with that question you pointed out about whether the president has the authority to not only shield 4.3 million undocumented immigrants from deportation, but also give them the ability to work, as well as benefits. And the conservative justices seemed very skeptical of that and seemed to believe that that's really the job of Congress, not the president. In fact, at one point, Justice Kennedy said this seems like the president coming up with a policy and Congress is executing it here. That's just upside-down. But, on the other hand, the liberal justices sided with the administration. There are 11 million undocumented immigrants in the United States. The Constitution gives the president prosecutorial discretion to manage immigration issues. And so the administration argues that's what it's doing here with these programs.
