Keith Olbermann on his stint at Current TV: 'I screwed up'

During an Tuesday night appearance on the Late Show with David Letterman, liberal political commentator Keith Olbermann addressed his abrupt exit from Current TV.

"I screwed up," he said. “I screwed up really big on this. Let’s just start there. I thought we could do this. It’s my fault that it didn’t succeed in the sense that I didn’t think the whole thing through."

"I didn’t say, ‘You know, if you buy a $10 million chandelier, you should have a house to put it in. Just walking around with a $10 million chandelier isn’t going to do anybody a lot of good, and it’s not going to do any good to the chandelier.'"

"And then it turned out we didn’t have a lot to put the house in to put the chandelier in, or a building permit, and I should have known that. And it is my fault at heart.”

Olbermann left MSNBC just over a year ago to join Current TV, a network owned by former U.S. Vice President Al Gore and businessman Joel Hyatt.

On March 20, the network dismissed him, citing "unauthorized absences" and other issues. Olbermann has promised legal action against his former employers.
