Employed chief journalist from across the Pond? (4)
I believe the answer is:
used
'employed' is the definition.
('use' can be a synonym of 'employ')
'chief journalist from across the pond?' is the wordplay.
I cannot quite understand how this works, but
'journalist' could be 'ed' (short for editor) and 'ed' is present in the answer.
The remaining letters 'us' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for used that I've seen before include "No longer pristine" , "Manipulated American editor" , "Previously owned by another" , "Utilised" , "cast off" .)
