Former White House press secretary Ari Fleischer predicted that CNN’s lawsuit against the Trump administration will “backfire” because its correspondent, Jim Acosta, has “pushed the envelope” of acceptable behavior by a reporter.

“Tension in the briefing room is natural and inevitable, but Acosta has pushed the envelope beyond what any reporter I’ve ever known has done,” Fleischer, who worked under former president George W. Bush, remarked Tuesday on Twitter. “I think CNN’s suit is a bad move that will backfire. Acosta Hill is the wrong one to die on.”
