After the Columbine shootings, O'Donnell became an outspoken supporter of gun control and a major figure in the Million Mom March. During the April 19, 1999, broadcast of her talk show, she stated, "You are not allowed to own a gun, and if you do own a gun, I think you should go to prison." O'Donnell previously had remarked, "I don't personally own a gun, but if you are qualified, licensed and registered, I have no problem." In May 1999, a month after the Columbine shootings, O'Donnell interviewed Tom Selleck, who was promoting "The Love Letter". O'Donnell interrogated him about his recent unpaid commercial for the National Rifle Association (NRA) and questioned him about the NRA's position on the use of "assault weapons." She said at the end of the segment the conversation had "not gone the way I had hoped" and added "if you feel insulted by my questions, I apologize because it was not a personal attack. It was meant to bring up the subject as it is in the consciousness of so many today." Ironically, O'Donnell at that time was a multi-million dollar paid spokesperson for 5 years for Kmart, which was the largest volume firearms retailer in the United States. Around the same time, the cast from "Annie Get Your Gun" was to appear on the show but refused O'Donnell's request to remove the line "I can shoot a partridge with a single cartridge" from the song "Anything You Can Do" and agreed to perform "My Defenses Are Down" instead.
