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 U.S. economy grew at a 2.5 percent annual rate in the first quarter of 2013, the Bureau of Economic Analysis estimated Friday morning.

That's modest growth, and was below the 3.2 percent pace economists had expected to hear about. But growth was up substantially from fourth-quarter 2012, when the economy expanded at a scant 0.4 percent annual rate.

An estimated 38 people died early Friday at a psychiatric hospital north of Moscow when a fire swept through the facility.

Dzhokhar Tsarnaev, the surviving suspect in the April 15 Boston Marathon bombings and the crimes that followed, has been moved out of Boston's Beth Israel Deaconess Medical Center "and is now confined at the Bureau of Prisons facility FMC Devens at Ft.
