Mark Memmott, NPR

Mark Memmott joined NPR News in the spring of 2009 to launch a new blog, "The Two-Way," with co-blogger Frank James.

"The Two-Way" is the place where NPR.org gives readers breaking news and analysis — and where it engages users in conversations ("two-ways") about the most compelling stories being reported by NPR News and other news media.

Memmott came to NPR from USA Today, where for over 20 years he worked as a reporter and editor on subjects ranging from politics and, foreign affairs to economics and the media.

In recent years he helped launch and then led three different news blogs at USATODAY.com, including the website's 2008 presidential campaign blog, On Politics.

Health and Human Services Secretary Kathleen Sebelius, who has borne the brunt of criticism for the troubled rollout of the HealthCare.gov website, said Friday that as she prepares to leave that agency she is thankful to have had the chance to work on "the cause of my life."

Her agency, Sebelius said, has been "in the front lines of a long overdue national change — fixing a broken health system."
