Mark Memmott

Mark Memmott is NPR's supervising senior editor for Standards & Practices. In that role, he's a resource for NPR's journalists – helping them raise the right questions as they do their work and uphold the organization's standards.

As the NPR Ethics Handbook states, the Standards & Practices editor is "charged with cultivating an ethical culture throughout our news operation. This means he or she coordinates regular training and discussion on how we apply our principles and monitors our decision-making practices to ensure we're living up to our standards."

Before becoming Standards & Practices editor, Memmott was one of the hosts of NPR's "The Two-Way" news blog, which he helped to launch when he came to NPR in 2009. It focuses on breaking news, analysis, and the most compelling stories being reported by NPR News and other news media.

Prior to joining NPR, Memmott worked for nearly 25 years as a reporter and editor at USA Today. He focused on a range of coverage from politics, foreign affairs, economics, and the media. He reported from places across the United States and the world, including half a dozen trips to Afghanistan in 2002-2003.

During his time at USA Today, Memmott, helped launch and lead three USAToday.com news blogs: "On Deadline," "The Oval" and "On Politics," the site's 2008 presidential campaign blog.

Citing "severe disciplinary violations" connected to his wife's murder of a British businessman and other allegations of corruption, the Communist Party of China today expelled once prominent politician Bo Xilai and turned him over to "judicial organs" for prosecution, the state-controlled Xinhua News Agency reports.

"This is something we see on the news in other parts of the country, not here," Minneapolis Deputy Police Chief Kris Arneson said Thursday night as her department began investigating why a man apparently walked into a sign company, killed at least four people and then took his own life.

On July 9, 2005, Adam Greenberg of the Chicago Cubs went to the plate for his first major league at bat.

One pitch later, his major league career was over.

Until now.

Israeli Prime Minister laid out in some detail this afternoon his nation's case for taking stronger action against Iran and his nation's response to what he said are "libelous" accusations about how Israel treats Palestinians.

Taking to the stage just minutes after the head of the Palestinian Authority, Benjamin Netanyahu told United Nations delegates this afternoon that Israelis and Palestinians "won't solve our conflicts with libelous speeches at the U.N."

Israel's government effectively rejects a "two-state solution" to its impasse with Palestinians and instead continues to wage a "campaign of ethnic cleansing" in the territories where his people live, Palestinian Authority President Mahmoud Abbas told delegates to the United Nations this afternoon.

The Zurich-based Mona Lisa Foundation said today that it has evidence that a painting that first came to light in the late 1800s is an early "Mona Lisa" also done by Leonard Da Vinci.

The 37-year-old search for Teamsters boss Jimmy Hoffa moves to a driveway in Roseville, Mich., on Friday.

"Police will be taking soil core samples," the Detroit Free Press reports, after receiving what they say is a "credible" tip that around the time of Hoffa's 1975 disappearance someone was buried under what's now a driveway in a Roseville residential neighborhood.

Construction of the Ryugyong hotel in Pyongyang, North Korea, began in 1987 — but was halted for 16 years by a lack of funds. The still-unfinished 105-story skyscraper has become something of a symbol of that nation's "thwarted ambitions," as the BBC says.

A huge drop in demand for cars, aircraft and other transportation equipment pulled down orders for so-called durable goods in August, the Census Bureau says.

Orders fell 13.2 percent, "the largest decrease since January 2009."

He was in more than 100 films, including such classics as Spartacus and El Cid.

But actor Herbert Lom, who died in London today at the age of 95, is best known as the perpetually peeved, increasingly insane police chief Charles Dreyfus in the Pink Panther films.

When Israeli Prime Minister Benjamin Netanyahu addresses the U.N. General Assembly today he will "argue for the need to set a 'red line' for Iran's nuclear program," Reuters reports.

NPR's Michele Kelemen adds that Netanyahu has "been urging the Obama administration to spell out clear red lines that would trigger military action" against Iran if it appears to be near to developing or acquiring nuclear weapons.

The not-so-long, not-so-much of a national nightmare is over.

Regular NFL officials will be on the field starting with tonight's game now that the league and its referees union have reached tentative agreement on a new, eight-year contract.

A year ago, Omran Ben Shaaban was among the young men who helped capture Moammar Gadhafi as the former Libyan leader tried to hide in a drainage ditch.

Reinforcing some things you might have suspected, the Pew Research Center's Project for Excellence in Journalism and Internet & American Life Project, along with the Knight Foundation, report today that a national telephone survey of adults finds:

Criminals and cops looking to grab a slice of some tasty action are smuggling American cheese into Canada, according to the Canadian Broadcasting Corp.

At the center of this "mozzarella mafia" conspiracy are some officers in the Niagara Regional Police Service, the news agency says. It says that:

While the number of new homes sold in August was barely changed from July, the median sales price was up sharply, the Census Bureau and Department of Housing and Urban Development report. So the news adds to other recent signs, including Tuesday's report about higher home prices in major cities, of a recovering housing sector.

Singer Andy Williams, best known for his rendition of Moon River, his Christmas TV specials and his long-running show in Branson, Mo., has died.

He was 84.

Williams' publicist, Paul Shefrin, says in a statement sent to reporters that the singer "passed away last night (Tuesday) at home in Branson, Mo, following a year long battle with bladder cancer. ... Williams, 84, who also had a residence in La Quinta, Calif., is survived by his wife Debbie and his three children, Robert, Noelle and Christian."

In something of a swan song, Iranian President Mahmoud Ahmadinejad used his eighth — and likely final — appearance before the U.N. General Assembly to elaborate on his vision of a new world order and criticize what he calls the world's "hegemonic" and "expansionist" powers.

In general, the Iranian leader took a less confrontational tone than in previous years.

Though the nation's football fans — from President Obama and Republican presidential nominee Mitt Romney to the average couch quarterback — are begging the two sides to settle their contract dispute so that regular NFL referees can come back to work, there seems to be no clear reason to think that's going to happen in time for this week's games.

Riot police in Athens have fired tear gas at protesters who in turn have been lobbing stones and petrol bombs in one of the largest anti-austerity demonstrations to hit the Greek capital in months.

The CIA tells Pakistan in advance about "broad areas" where it intends to take aim at suspected terrorists with drone strikes and interprets the other government's silence and clearing of airspace as "tacit consent," The Wall Street Journal reports this morning.

Saying its sources are "U.S. officials" and "two senior [Obama] administration officials," the Journal adds that:

New Orleans is known for being different. The trial of the man accused in the 2010 murder of "social-media celebrity Anthony Barre, better known as Messy Mya," is adding to the city's reputation.

As The Times-Picayune reports, the trial was halted Monday after the district attorney's office "got wind of a YouTube video of the 7th Ward slaying and dropped the murder charge against Jason Baptiste Hamilton in an attempt to track down the footage."

Saying it "must be called by its true name, 'modern slavery,' " President Obama this afternoon used his address before the Clinton Global Initiative to focus on "the outrage of human trafficking."

When a man is "working, toiling for little or no pay and [is] beaten if he tries to escape, that is slavery," Obama said.

"When a woman is locked in a sweat shop or trapped in a home as a domestic servant ... that is slavery."

Using the example set by the life of slain U.S. Ambassador to Libya Chris Stevens, President Obama this morning told delegates to the United Nations that the diplomat's killers will not determine the world's future. Instead, Obama said, it will be people such as Stevens who build "bridges across oceans and cultures" and set the world's agenda.

Saying that foreign aid must play a role in bringing peace to the Middle East, Republican presidential nominee Mitt Romney made the case today for what he calls "prosperity pacts" that would aim U.S. assistance packages at nations that develop "the institutions of liberty, the rule of law, and property rights."

Romney was addressing the Clinton Global Initiative in New York, a forum that will host President Obama later today.

If he's elected in November, Romney said (per his prepared remarks):

Home prices rose in July from June by 1.5 percent in its 10-city index and 1.6 percent in the 20 major cities where it tracks changes, the latest S&P/

Unfortunately, this news is not a surprise:

"As Syria's civil war has intensified, thousands of children have died in brutal attacks and many more have been injured, traumatized or forced to flee their homes," the international charity Save the Children reports. And it warns that "boys and girls continue to be killed, maimed and tortured. These appalling violations against children must stop and those carrying them out held to account."

"President Barack Obama will warn Iran on Tuesday that the United States will 'do what we must' to prevent it from acquiring a nuclear weapon, and appeal to world leaders for a united front against further attacks on U.S. diplomatic missions in Muslim countries," Reuters reports this morning.

Update at 8:30 a.m. ET. According to excerpts released by the White House, the president will say:

Football fans are furious. Bettors are out an estimated $150 million. Gov. Scott Walker of Wisconsin — the Republican who's famous for battling with organized labor — is on the side of the referees union. And the NFL is in something of a "prevent defense," saying that nothing can be done to change the outcome.
