The morning after a stinging defeat in South Carolina, former Massachusetts Gov. Mitt Romney said he would release his most recent tax returns this week, ahead of the Florida primary.

Romney said he would release his 2010 tax returns and an estimate of what he'll pay for 2011 on Tuesday. "We made a mistake in holding off as long as we did," he told Fox News Sunday.

Joe Paterno, the longtime Penn State coach who won more games than anyone in major college football but was fired amid a child sex abuse scandal that scarred his reputation for winning with integrity, died Sunday. He was 85.

His family released a statement Sunday morning to announce his death: "His loss leaves a void in our lives that will never be filled."

Hispanic voters are a key group in the presidential race, and Republican hopeful Mitt Romney has been reaching out to them. Should he tell them that he himself is the son of an immigrant from Mexico?

Romney's father, George, was born in the state of Chihuahua, in a colony of polygamous Mormons.

Romney rarely speaks about the Mexican branch of his family, and he's never visited his numerous cousins south of the border — but the Romneys of Mexico are all rooting for him.

Arab foreign ministers are meeting in Cairo on Sunday to decide whether or not to continue the Arab League's monitoring mission in violence-torn Syria. Host Rachel Martin talks with NPR's Lourdes Garcia-Navarro.

Former Speaker Newt Gingrich is the winner of the South Carolina Republican presidential primary. Former Massachusetts Gov. Mitt Romney placed second. NPR's Debbie Elliott talks with South Carolina voters about who they voted for in Saturday's primary and how they made their decisions.

As technology gets better — and cheaper — it's becoming easier for authoritarian governments to watch and record their populations' every move. John Villasenor of the Brookings Institution joins host Rachel Martin to discuss the phenomenon.

Klubradio is one of Hungary's only remaining independent broadcasters, but it may soon go silent. The station's struggles are emblematic of the Hungarian government's crackdown on civil liberties. The European Union is so worried that last week it issued a warning to Hungary: Revise your new constitution to comply with EU laws or leave the EU.

Komotini is a village in the Greek province of Thrace. Its Muslim population dates back to the time of Ottoman occupation. They still speak Turkish and Shariah law still applies to Muslim residents in family matters, a state of affairs that has inflamed some politicians in Athens. Meanwhile, residents say their bigger problem is poverty.

NPR's Ari Shapiro reports on former Massachusetts Gov. Mitt Romney, who came in second in South Carolina's Republican primary on Saturday.

On Jan. 12, for the second anniversary of the devastating earthquake, thousands of people flocked to the Shalom Church in Port au Prince, Haiti. The "church" is just a plywood stage under a patchwork of tattered tarps.

The crowd was so large that it spilled down a muddy hill toward a tent camp for earthquake victims. Most of the singing, swaying congregation were so far away they couldn't even see the podium.

The evangelical mission now claims to have more than 50,000 members and one of the most popular radio stations in Haiti.

An Islamist party heads Morocco's newly elected government, part of a wave of Islamist election victories following uprisings across North Africa.

But Morocco's case is a bit different. King Mohammed VI responded quickly to a pro-democracy movement last year with a new constitution and snap elections. The Justice and Development Party, known as the PJD, won the most votes in November. Now, Moroccans ask: How will this popular Islamist party govern?

Secrets: the currency of spies around the world. The rise of social media, hash-tags, forums, blogs and online news sites has revealed a new kind of secret — those hiding in plain sight. The CIA calls all this information "open source" material, and it's changing the way America's top spy agency does business.

By embracing Newt Gingrich in its primary, the South Carolina GOP has risked its remarkable record of success at picking the party's eventual nominee for president.

It's been quite a run. Beginning with its primary in 1980, when it chose Ronald Reagan, South Carolina has voted first among Southern states. And the Palmetto State's choice has gone on to dominate the other Southern states and lock up the nomination in short order. That happened eight times in a row, counting incumbent renominations.

There are water fountains, park benches, churches and expensive restaurants and then there are presidential candidates' headquarters, now making the list of places to take wedding photos.

Especially if you're a part of this wedding party getting hitched on primary day in South Carolina.

NPR's Don Gonyea tweeted this photo of the bride and her bridesmaids while preparing to cover the results of Saturday's first-in-the-South vote.

Newt Gingrich has beaten Mitt Romney in South Carolina. The question now becomes whether he can pull off that trick enough times in enough states to deny Romney the Republican presidential nomination.

It was a big win for Gingrich, the former House speaker, who took 40 percent of the vote, compared to 28 percent for Romney, a former Massachusetts governor.

South Carolinians are voting today in the GOP primary, which some pundits see as the candidates' last stand for getting the GOP nomination to run in the general election.

On weekends on All Things Considered today, host Guy Raz talked with Danielle Vinson, the chair of the political science department at Furman University in Greenville, S.C., about what is often considered "dirty" South Carolina primary politics.
