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.

Funerals began Thursday for the 24 people known to have been killed by the tornado that devastated Moore, Okla., on Monday.

A male sergeant at West Point has been accused of secretly videotaping at least a dozen female cadets, sometimes when they were showering, The New York Times reports.

Gen. John F. Campbell, the army's vice chief of staff, tells the Times that "once notified of the violation, a full investigation was launched, followed by swift action to correct the problem."

"I have not done anything wrong. I have not broken any laws. I have not violated any IRS rules or regulations."

That was the word Wednesday morning from Lois Lerner, the Internal Revenue Service official at the center of the political storm over the agency's targeting of some conservative groups that were given extra scrutiny from 2010 into 2012.

In Orlando, Fla., early Wednesday "an FBI agent was involved in a deadly shooting connected to the Boston Marathon bombing case," NBC News is reporting. A man who was being questioned by the agent is dead. NPR's Dina Temple-Raston and Carrie Johnson have also confirmed the news.

Just how firm the man's alleged connection to the marathon case is, though, remains unclear.

The next mayor of Los Angeles will be City Councilman Eric Garcetti.

In a race in which the two top contenders were both Democrats, the 42-year-old Garcetti has opened a 7- to 8-percentage-point lead over City Controller Wendy Greuel as Tuesday's votes are being counted.

Former New York Rep. Anthony Weiner, whose career appeared to famously flame out in 2011 when he resigned from Congress because of an extramarital sexting scandal and his lies about what he'd done, has now officially jumped back into politics.

The news Wednesday from Moore, Okla., much of which was destroyed by a massive tornado Monday, begins with word that officials doubt they will find any more survivors or bodies under the hundreds of homes, businesses and other buildings that were leveled.

We don't need to say much. Just watch this video from The Oklahoman of Trenda Purcell's reunion Monday with her 8-year-old son Kamden, who she found safe and sound after the tornado that swept through Moore, Okla.

Facing questions for the first time about why Internal Revenue Service personnel singled out some conservative groups for inappropriate scrutiny while he was head of the agency, former IRS Commissioner Douglas Shulman told Congress on Tuesday that "I was dismayed and I was saddened" to learn about what had happened under his watch.

Both the former IRS commissioner who was in charge when the agency singled out some conservative groups for extra scrutiny and the man who replaced him will be appearing at a Senate Finance Committee hearing Tuesday morning.

Douglas Shulman, an appointee of President George W. Bush who left the IRS last November, and acting commissioner Steven Miller (who is losing his job because of the scandal) are due at the 10 a.m. ET hearing.
