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.

Former Italian Prime Minister Silvio Berlusconi was ordered Tuesday to spend at least four hours a week for the next year doing community service at a center for the elderly, NPR's Sylvia Poggioli tells our Newscast Desk.

One of the least imaginative, but always popular, stories for an editor to assign in years past was the annual Tax Day frenzy at the local post office.

Younger Two-Way readers may not know this, but before e-filing was the thing to do, many procrastinators would wait until the last possible moment to finish their federal tax returns. And many post offices would keep staff on hand until midnight so that those returns could be postmarked before April 15 turned into April 16.

Now?

The crisis in Ukraine has taken on even more of a Cold War-era feel after a Russian warplane made nearly a dozen low passes over the weekend of a U.S. destroyer that was sailing in the Black Sea.

Col. Steve Warren, a Pentagon spokesman, calls the Russian flybys "provocative and unprofessional," NPR's Tom Bowman reports.

According to the Pentagon, the Russian SU-24 attack aircraft came within several thousand feet of the USS Donald Cook on Saturday and ignored multiple radio warnings from the ship.

"A deadline set by the Ukrainian government for pro-Russian gunmen to leave government buildings in eastern Ukraine and surrender weapons passed early Monday," The Associated Press writes, "with no immediate sign of any action to force the insurgents out."

On Day 38, the latest developments in the search for Malaysia Airlines Flight 370 come from the surface of the Indian Ocean and more than 2 miles beneath on the sea floor.

A highway in Northern California was turned into an inferno Thursday when a FedEx truck slammed into a charter bus full of high school students.

Hillary Clinton was not struck Thursday when a woman threw a shoe at the former secretary of state while she was on stage in Las Vegas giving the keynote speech at conference hosted by the Institute of Scrap Recycling Industries.

Pope Francis asked Friday for forgiveness from the victims of pedophile priests in some of his strongest words to date about the Catholic Church's sex abuse crisis.

NPR's Sylvia Poggioli reports from Rome that:

"The pope has come under fire from advocacy groups for a perceived lack of attention to the issue.

Hopes were both raised and lowered Friday by officials involved in the search for Malaysia Airlines Flight 370. The jet and the 239 people on board have now been missing for five weeks.
