Oprah Cuts Vacation Short to Go Back to Work

Oprah Winfrey is cutting her vacation short to get her new cable network back on track.

Oprah, who had jetted to London after wrapping her legendary talk show last month, was back in Chicago to focus on the Oprah Winfrey Network, which is facing disappointing ratings.

"The vacation that I thought that I was going to have is over," Winfrey told a cable TV convention. "I need to be there. I need to be engaged and involved."

About her troubled network she said, "I have committed everything I have to this. I wouldn't bet against me."
