The Trump administration removed CNN from its duties as the pool representative for television networks on Monday, days after barring journalists from CNN, MS NOW and Politico from the White House. CNN had been scheduled for TV pool duties this week as part of a longstanding agreement among five major television networks to share responsibility for covering the president’s activities.

On Friday, President Trump announced he was barring the three outlets from the White House, calling their coverage "purposely negative." Journalists from the organizations had their badges confiscated when they arrived on Saturday. Five networks — ABC, CBS, CNN, NBC and Fox News — rotate as the designated television outlet covering presidential events.

CNN had been slated to provide coverage during Mr. Trump’s travel to New York, where he is scheduled to address the United Nations General Assembly this week. It was unclear whether another TV network would be designated to take CNN’s place. CNN, MS NOW and Politico said they would sue the Trump administration, saying the ban violated their First Amendment rights. Experts say the president’s ban is unlikely to withstand legal scrutiny.
