Oprah Winfrey has cancelled Monday’s episode of The Oprah Winfrey Show. The Queen of Talk announced on her Web site this morning that she has pulled an episode of her show, titled 10 Years Later: The Truth about Columbine, that was to look back at the shootings that took place at Columbine High School in Colorado ten years ago today.

“I decided to pull the Columbine show today. After reviewing it, I thought it focused too much on the killers,” Oprah wrote. “Today, hold a thought for the Columbine community. This is a hard day for them.”

Today marks the anniversary of the massacre in Littleton, Colorado that killed 12 students and a teacher.
