Newsman covering US workers worried in greater detail (10)

I believe the answer is:

elaborated

'in greater detail' is the definition.

'newsman covering us workers worried' is the wordplay.
'newsman' becomes 'ed'.
'covering' means one lot of letters goes inside another.
'us workers' becomes 'labor' (US spelling of 'labour').
'worried' becomes 'ate' (something worrying may eat someone up).
'labor'+'ate'='laborate'
'ed' going around 'laborate' is 'ELABORATED'.

(Another definition for elaborated that I've seen is " Added detail to (an account)".)

I've seen this clue in The Independent.
