Insist on reporters (5)
I believe the answer is:
press
I believe this is a double definition.
'insist on' is the first definition.
(thesaurus)
'reporters' is the second definition.
(members of the press)
(Other definitions for press that I've seen before include "Impel" , "Newspapers - cupboard" , "(Of time) be short" , "Crush; iron" , "Journalists - crowd" .)
