Note journalists keep back (7)
I believe the answer is:
repress
'keep back' is the definition.
(thesaurus)
'note journalists' is the wordplay.
'note' becomes 're'.
'journalists' becomes 'press' (I've seen this before).
're'+'press'='REPRESS'
(Other definitions for repress that I've seen before include "Subdue" , "Curb" , "keep back" , "Silence" , "Check" .)
