ABC News has apologized after a high-profile news anchor reported on Twitter that US President Barack Obama called rapper Kanye West a "jackass" in an off-the-record conversation.
The comment, from an off-the-record portion of an interview by US business channel CNBC, was tweeted to one million followers on the micro-blogging site by "Nightline" anchor Terry Moran. The tweet was later deleted.
"In the process of reporting on remarks by President Obama that were made during a CNBC interview, ABC News employees prematurely tweeted a portion of those remarks that turned out to be from an off-the-record portion of the interview," said ABC News in a statement late Monday.
"This was done before our editorial process had been completed. That was wrong. We apologize to the White House and CNBC and are taking steps to ensure that it will not happen again."
ABC News senior vice president Jeffrey Schneider said that the organization had reached out to the White House and CNBC in a series of telephone calls.
"It was a mistake. It's certainly one that we regret. We certainly made that very clear to CNBC and the White House," he said.
