And now, let's get down to the campaign trail. In the race for the Republican nomination, the scene has shifted to Louisiana which is holding its primary tomorrow. Today, all four of the remaining GOP candidates are campaigning in the state.
Most of the media focus is on Rick Santorum and Newt Gingrich. Both men have won other southern primaries, and both have been in and out of Louisiana all week long, hoping a victory there will keep their slim chances of winning the GOP nomination alive. Here's NPR's Brian Naylor.
It's MORNING EDITION from NPR News. Good morning. I'm David Greene.
As many of you know, prices at the gas pump are still rising. That can often spell trouble, politically, for a sitting president. And President Obama has spent much of this week touting different kinds of energy as the solution to price spikes. Out on the road, Mr. Obama has promoted a mix of fossil fuels, alternative energy and greater fuel efficiency. Along with solar and wind power, Mr. Obama says brain power can help to reduce America's dependence on foreign oil.
Let's go now to Florida, where late yesterday Governor Rick Scott announced that a new state attorney has been assigned to investigate the shooting death of Trayvon Martin. The announcement came as thousands rallied in Sanford demanding justice for Martin. The teen was shot as he walked unarmed in Sanford, a suburb of Orlando. The shooter, George Zimmerman, is a volunteer neighborhood watch captain and he claims self-defense. He's also not been arrested. As NPR's Kathy Lohr reports, the cry is growing louder for an arrest to be made.
Now, even if the shooter, George Zimmerman, is arrested for the death of Trayvon Martin, a conviction could be hard to get because of the controversial law that Kathy mentioned in her report. Let's take a closer look at that law. It's called Stand Your Ground and it allows people to use deadly force to defend themselves when confronted with a threat of violence. It's been on the books in Florida for several years. And as NPR's Greg Allen reports from Miami, it was a source of controversy long before the Martin shooting.
North Korea agreed, last month, to freeze uranium enrichment and missile tests in exchange for large amounts of food aid from the United States. American officials thought they had an understanding, but then last week North Korea announced it would be launching a satellite using a long-range missile. As NPR's Mike Shuster reports from Seoul, all this is now threatening to overshadow next week's global nuclear security summit in Seoul, which President Obama is planning to attend.
