It is unclear who is telling the truth. But CNN filing a lawsuit seems plausible, and Donaldson seemed pretty confident. If a lawsuit has not been filed yet, it looks like one is likely in the near future.
CNN may be gearing up for a legal battle over the Trump administration's revocation of chief White House correspondent Jim Acosta's permanent press credentials.
Former ABC News reporter and anchor Sam Donaldson appeared Sunday on CNN's "Reliable Sources" and said he believed a lawsuit had already been filed.
"I hope I'm not mistaken, but it's my understanding that CNN and Acosta have sued, that there will be a court hearing on Tuesday on this very matter that we've been discussing," Donaldson said.
A CNN spokesperson told the Washington Examiner that a lawsuit has not been filed yet. "No decisions have been made. We have reached out to the White House and gotten no response," the spokesperson said.
