Brian Ross, the ABC chief investigative reporter, has been suspended by the US news network after he made a “serious error” about Donald Trump’s former top aide, Michael Flynn.
The journalist reported Trump was a candidate when he directed Flynn to make contact with Russia.
He, however, clarified later that the orders came when Trump was president-elect.
The activities of Trump’s campaign team are under investigation over whether they colluded with Russia to help sway the election in his favour.
Flynn, on Friday, pleaded guilty to lying to the FBI about his contacts with Russian officials prior to the president’s inauguration in January.
Trump had sacked him as national security adviser in the wake of the allegation.
Flynn is reported to have agreed to co-operate, as part of plea bargain, with special prosecutor Robert Mueller’s investigation into possible collusion between the Trump campaign and Russia ahead of the 2016 election.
