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.

"Dozens of police in riot gear and hundreds of protesters supporting the Occupy Wall Street movement engaged in a game of cat-and-mouse in downtown Oakland on Tuesday," The Associated Press writes, "with authorities using tear gas to respond to demonstrators' repeated agitations."

The U.S.-NATO mission in Libya was a "recipe for success in the future," President Obama said Tuesday on NBC-TV's The Tonight Show with Jay Leno.

During a sober discussion that lasted several minutes, the president told Leno that he doesn't agree with critics who say the U.S. led from behind.

"The defining sound of the Occupy Wall Street" protests in Manhattan, as Weekend Edition Sunday's Audie Cornish has said, is "the never-ending drum circle."

Saying that it "reorders the way they do business in Washington by reinventing the tax code and restoring our nation to fiscal health through balanced budgets and entitlement reform," Texas Gov. Rick Perry is this hour unveiling his "cut, balance and grow plan" on taxes.

"Oakland police arrested dozens of people at a plaza outside City Hall and at a second, smaller camp nearby early this morning, two weeks after the protesters launched efforts as part of the nationwide Occupy Wall Street movement against corporate greed and economic inequality," The San Francisco Chronicle reports.

A sharp drop in a widely watched gauge of consumer confidence has brought that key economic barometer to a low "last seen during the 2008-2009 recession," Conference Board director of consumer research Lynn Franco says in a report released by the private research group this morning.

The board says its consumer confidence index fell this month to 39.8, from 46.4 in September. Other measures of consumer sentiment, about current conditions and expectations, also declined.
