September 11, 2001 was the first time The Oprah Show ever had to cancel a taping. The terrorist attacks in New York City, Washington, D.C., and Pennsylvania instantly transformed America into a nation in mourning. On September 13 and for the next several weeks, The Oprah Show highlighted the lives of people who had lost their lives, and helped Americans deal with the tragedy. "We will never forget," Oprah said.
Oprah has revisited the aftermath of 9/11 several times, from speaking with the children of victims of 9/11 in 2007 to asking former president George W. Bush about his reaction to the attacks.
