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.

There's a growing controversy in Sweden over whether Culture Minister Lena Adelsohn Liljeroth should have smilingly cut into a cake in the shape of a naked black woman during a World Art Day event over the weekend.

For telling National Rifle Association members over the weekend that "I will either be dead or in jail by this time next year" if President Obama is re-elected, rocker Ted Nugent has now attracted the attention of the Secret Service.

"We are aware of the incident, and we are conducting appropriate follow-up," Secret Service spokesman Brian Leary says.

Photos obtained by the Los Angeles Times that appear to show U.S. Army paratroopers posing with the remains of suicide bombers in Afghanistan "undermine the daily sacrifices of thousands of ISAF troops who continue to serve honorably in Afghanistan," the top U.S.

The must-read story of the day if you're into practical jokes has to be The Wall Street Journal's piece headlined "Walk The Prank: Secret Story Of Mysterious Portrait At Pentagon."

As Melissa Block and Audie Cornish will explain later on All Things Considered, last year some pranksters hung a portrait on a hall in the Pentagon with a plaque saying it was "Ensign Chuck Hord. USNA circa 1898. Lost at sea 1908."

There is no such person.

Chrysler, Ford and General Motors gained market share in the past couple years. Helped by Toyota's much-publicized recalls, the problems that Japanese carmakers faced after last year's earthquake and tsunami, and an improving reputation for the quality of American-made vehicles, Detroit's Big Three grabbed 47 percent of sales last year — up from 45.1 percent in 2010 and 44 percent in 2009.

Our friend Micki Maynard of Changing Gears, though, reports that the Detroit companies' comeback — in terms of market share — may be over.

How bad are things at the General Services Administration, where the scandal over extravagant spending at a Las Vegas conference has led to resignations, firings and could end up with criminal charges for some officials?

The "summit scandal" continues to grow, judging from this story just posted by Reuters:

"Twenty or 21 women were brought back to the hotel in Colombia by U.S. Secret Service agents and members of the U.S. military in an incident last week involving alleged misconduct with prostitutes, U.S. Senator Susan Collins said on Tuesday."

For those who can't get enough of polls about the presidential election, Gallup has fired up its "daily tracking" survey that will follow the levels of support for President Obama and presumed GOP nominee Mitt Romney.

And it begins with:

-- Romney's support among registered voters at 47 percent.

-- Obama's support among registered voters at 45 percent.

There was a 5.8 percent drop in housing starts from February to March, the Census Bureau and Department of Housing and Urban Development just reported.

Bloomberg News says the decline was unexpected and left starts at a five-month low.

Still, the number of starts was up 10.3 percent from March 2011.
