Republicans originally redacted models' faces (7)
I believe the answer is:
opposes
'faces' is the definition.
(opposing is a kind of facing)
'republicans originally redacted models'' is the wordplay.
'republicans' becomes 'gop' (the Grand Old Party, nickname for US Republicans).
'originally redacted' means to remove the first letter (the origin of the word is redacted).
'models'' becomes 'poses' ('pose' can be a synonym of 'model').
'gop' with its initial letter taken away is 'op'.
'op'+'poses'='OPPOSES'
(Other definitions for opposes that I've seen before include "Disagrees with and attempts to prevent" , "Strongly disapproves" , "Goes against" , "Counters" , "Stands against" .)
