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 news blogs: "On Deadline," "The Oval" and "On Politics," the site's 2008 presidential campaign blog.

The news that China's Foreign Ministry now says legal activist Chen Guangcheng can apply to study abroad could be an "elegant solution [of] a really difficult diplomatic problem," NPR's Louisa Lim reported earlier on Morning Edition.

Chen has "a letter of invitation" from New York University, she says.

Artist Candy Chang turned the wall of an abandoned house in New Orleans into "a giant chalkboard where residents can write on the wall and remember what is important to them."

And since putting up that public art project in February 2011, "Before I Die" walls have spread to at least 19 cities around the world. Friday, a wall goes up in Denver.

Before his escape from house arrest, his stay at the U.S. embassy in Beijing and now his plea that he be allowed to go to the U.S., Chinese legal activist Chen Guangcheng was the focus of a "Dark Glasses" campaign aimed at drawing attention to his plight.

Al-Qaida leader Osama bin Laden was frustrated with "regional jihadi groups and his seeming inability to exercise control over their actions" in the last few years before he was killed by U.S. Navy SEALs.

That's "the most compelling story to be told," according to an analysis of some documents seized from bin Laden's Pakistani compound in the May 2011 raid that ended with his death, West Point's Combating Terrorism Center reported today.

There were 365,000 first-time claims for unemployment insurance filed last week, down 27,000 from the week before, the Employment and Training Administration reports.

While the signs so far point to suicide, there aren't yet any really revealing clues to why former NFL star Junior Seau apparently killed himself Wednesday.

About all there is so far is a hint that, in retrospect, Seau may have said some goodbyes. The San Diego Union-Tribune reports that:

The fate of Chinese legal activist Chen Guangcheng remains uncertain one day after he left the U.S. embassy in Beijing.

San Diego's Union Tribune reports that former NFL linebacker Junior Seau "has died from an apparent self-inflicted gunshot wound at his beachfront home."

It adds that:

"Chargers chaplain Shawn Mitchell said he was notified of the death and is on his way to be with family members."

Saying "I never could have predicted either the low points or the high points," former House Speaker Newt Gingrich just officially suspended his bid for the 2012 Republican presidential nomination.

He's been leading up to this for more than a week. Tuesday, he posted a video to say goodbye to his supporters.

Update at 4:30 p.m. ET. Romney On Gingrich:

Daniel Chong, a California college senior who "was left alone in a federal holding cell for five days with no food or water," now at least has an apology from the Drug Enforcement Adminstration.

That likely won't make up for having to drink his urine to survive, as Chong spoke of to reporters on Tuesday.
