Federal agents interviewed new witnesses this week in an ongoing investigation of government scientists that's been called "polar bear-gate," according to the scientists' lawyer.
The controversial probe, now entering its third year, is looking into allegations of scientific misconduct related to a 2006 report by wildlife researchers Charles Monnett and Jeffrey Gleason, who described seeing dead polar bears floating in Arctic waters.
We're going to look now at an animal whose habitat is slowly disappearing. Polar bears live on sea ice. But Arctic sea ice, which used to stay frozen in the summertime, is now slowly disintegrating. This poses a unique challenge for scientists, government officials and others. How do you preserve the polar bear and prevent it from going extinct decades from now? Juliet Eilperin of The Washington Post has been reporting on this issue. And she joins us now to talk about what she's learned.
