United States news network ABC News on Saturday suspended its chief investigative reporter Brian Ross for four weeks after he made an error about United States President Donald Trump’s former National Security Advisor Michael Flynn.

Ross had reported on Friday that Trump was a candidate for the 2016 US presidential elections when he asked Flynn to make contact with Russia. However, he later clarified that Trump issued the order when he was the president-elect.

Flynn on Friday admitted to the Federal Bureau of Investigation that he had contacts with Russian authorities, and said he would cooperate with their inquiry into Moscow’s allged attempts to influence the 2016 election.

Though ABC News apologised, Trump lashed out on Sunday, calling on people who lost money on the stock market to sue the news network.
