[article] (CNN) -- The "tweet heard round the world" was followed by the sound of a slamming door Saturday. Media company IAC has "parted ways" with the company PR executive who tweeted: "Going to Africa. Hope I don't get AIDS. Just kidding. I'm white!" IAC spokesman Ryan Trostle said Saturday: "The offensive comment does not reflect the views and values of IAC. We take this issue very seriously, and we have parted ways with the employee in question. "There is no excuse for the hateful statements that have been made and we condemn them unequivocally," he said. "We hope, however, that time and action, and the forgiving human spirit, will not result in the wholesale condemnation of an individual who we have otherwise known to be a decent person at core." Justine Sacco's tweet went viral while she was en route to South Africa. Sacco did not immediately respond to messages left by CNN. The tweet Justine Sacco sent before she left Friday for Cape Town, South Africa, went viral and created a social media firestorm.
