Why Don't High Profile Journalists Pull An Oprah on Bush?

An article on Anti-War.com, by Norman Solomon reports the confrontation between Oprah and Frey and comments:

When Frey tried to weasel out of responsibility for concocting a phony story about a root canal without anesthetic, the host interrupted after the words "I've struggled with the idea of it –"

"No, the lie of it," Winfrey said. "That's a lie. It's not an idea, James, that's a lie."

But high-profile journalists are unwilling to confront President Bush on national television with such clarity: "That's a lie. It's not an idea, George, that's a lie."

Wouldn't that be sweet?
