On April 20, 1999, CNN was covering Clinton's speech in Littleton, Colorado, following the Columbine High School massacre. Dobbs ordered the producer to cut away from the speech and return to broadcast "Moneyline". Dobbs was countermanded by Kaplan, who ordered CNN to return to the speech. Kaplan later said, "Tell me what journalistic reason there was not to cover the president at Columbine soon after the shootings? Everyone else was doing it". Dobbs announced on the air that "CNN President Rick Kaplan wants us to return to Littleton". A few days later, Dobbs announced that he was leaving the network to start Space.com, a website devoted to astronautical news. Dobbs was subsequently replaced as host of "Moneyline" by Willow Bay and Stuart Varney.
