"An unfortunate and inappropriate remark was made by one of our producers off camera yesterday," a CNN spokesperson told Business Insider in a statement.
"We have apologised to the Trump transition team, and the producer has been disciplined," the spokesperson said.
As correspondent Suzanne Malveaux prepared for a live shot at Carrier's Indianapolis plant on Thursday, a producer was heard discussing various hand signals with her.
"That means his plane's crashed - just kidding," the producer said, prompting a stunned face from Malveaux.
During the campaign he referred to the outlet as the "Clinton News Network" and, according to reports, criticised its president during a recent closed door meeting with top television executives.
