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.

Tens of thousands of people are protesting in all of Pakistan's major cities today, NPR's Jackie Northam reports from Islamabad, as those who oppose U.S. policy in the region continue to use outrage over an anti-Islam video to whip up anti-American sentiment.

Fifteen members of an Amish breakaway group in Ohio "have been found guilty of hate crimes by carrying out beard- and hair-cutting attacks against fellow Amish in a dispute over religious differences," The Associated Press reports.

This may be one of the last developments in the story of the "pepper spray cop" and what happened last November when University of California Davis Police Lt. John Pike infamously blasted some Occupy protesters who were blocking a campus road with some tear-inducing gas:
