“Through conversations and advocacy, we urged CNN to grant access to at least one print pool reporter for the duration of the debate,” the group wrote in a statement Thursday.

Currently, CNN rules state that a pool of still photographers will be allowed in the studio, but a print pool reporter will be given access during commercial breaks.

“That is not sufficient in our view and diminishes a core principle of presidential coverage,” the statement says. “The White House pool has a duty to document, report and witness the president’s events and his movements on behalf of the American people.”
