Revealing report about Rhode Island (6)
I believe the answer is:
baring
'revealing' is the definition.
(thesaurus)
'report about rhode island' is the wordplay.
'report' becomes 'bang' (I've seen this before**).
'about' indicates putting letters inside.
'rhode island' becomes 'ri' (US postal abbreviation).
'bang' going around 'ri' is 'BARING'.
(Other definitions for baring that I've seen before include "Exposing" , "Stripping or uncovering" .)
