The death of Trayvon Martin, an unarmed teen who was shot and killed by neighborhood watch volunteer George Zimmerman, has sparked nationwide demonstrations and school walkouts. It has also prompted new conversations about race in America.

In a sign that his campaign is in need of cash, Newt Gingrich began charging supporters $50 if they wanted him to pose for a picture.

The National Journal first reported the story, saying the campaign began the practice Monday.

Here's some of the early word about today's Supreme Court hearing on the constitutionality of the nation's new health care overhaul law:

-- Five Justices Were Tough: Five members of the court "beat him up pretty hard," NPR's Nina Totenberg says of how the justices treated the counsel representing the government. But she also says, "I don't think you can call this," when asked about whether the court will or won't strike down the so-called individual mandate in the law. Chief Justice John Roberts and Justice Anthony Kennedy "seem to be in play," Nina reports.

Today's arguments hit the core of the Affordable Care Act: the mandate that requires just about everyone to have health insurance starting in 2014.

And the U.S. Supreme Court's justices appeared split on whether the federal government can force people to buy health insurance. The court's conservatives appeared skeptical and unmoved by the government's arguments in favor of the mandate.

"The government had a hard time, and if they win, they win narrowly," NPR's Nina Totenberg reported from outside the court. "I don't think you can call this."

The Trayvon Martin case is bringing conversations about race to the front pages, the airwaves, and dinner tables. Even the president weighed in on the shooting last week. But freelance journalist Reniqua Allen writes in The Washington Post that having a black president is making those conversations harder to have, not easier.

There's new information in the shooting of Trayvon Martin, the 17-year-old Florida boy who was fatally shot by George Zimmerman last month. Zimmerman told police that Martin assaulted him, and a family spokesman confirms Martin was suspended from school at the time of his death. Guest host Jacki Lyden speaks with Miami Herald reporter Frances Robles.

Senegal and Mali have experienced recent upheaval. Guest host Jacki Lyden talks with NPR's West Africa correspondent, Ofeibea Quist-Arcton about the rebellion and coup d'etat in Mali, as well as the recent news that the Senegalese president conceded a very controversial election.

JACKI LYDEN, HOST:

I'm Jacki Lyden and this is TELL ME MORE from NPR News. Michel Martin is away this week. Coming up, after a successful presidential runoff in Senegal and a military overthrow in Mali, we'll talk about questions of leadership in West Africa. That's coming up.

But, first, we turn our attention to Cuba, where Pope Benedict is continuing his tour of Latin America. He's in the midst of a three day visit to the island. Tens of thousands of people greeted him in Santiago last night.
