American journalist that's taken advantage of (4)
I believe the answer is:
used
'taken advantage of' is the definition.
(I've seen this before)
'american journalist' is the wordplay.
'american' becomes 'us'.
'journalist' becomes 'ed' (short for editor).
'us'+'ed'='USED'
'that's' acts as a link.
(Other definitions for used that I've seen before include "no stranger" , "Second-hand; exploited" , "took a chance on becoming dependent" , "That's not new" , "with some traffic" .)
