Norah O'Donnell on moving "CBS Evening News" to Washington, D.C.

"CBS Evening News" anchor Norah O'Donnell feels she's returning to her roots as a reporter now that "Evening News" is based in Washington, D.C. It launched this week, the only evening news broadcast to originate from the nation's capitol.

"It's my background, being a reporter. This allows me in some ways to return back to my roots and my strengths," said O'Donnell, who began her career as a journalist in Washington. "Just about every decision that affects our lives has a nexus in Washington."

She also looked back at the legacy of Edward R. Murrow, a storied CBS News journalist perhaps best known for his incisive reports on Senator Joseph McCarthy.

"What journalism can do is not only inspire but it can also hold the powerful accountable. It can expose abuse. It can expose corruption," O'Donnell said. "We're tough on the president. We're tough on members of Congress. Because we're supposed to be."
