Found out bent Republican is inside (7)
I believe the answer is:
learned
'found out' is the definition.
('learn' can be a synonym of 'find out')
'bent republican is inside' is the wordplay.
I cannot really see how this works, but
'republican' could be 'r' (abbreviation in US politics) and 'r' is located in the answer.
'bent' could be 'leaned' (leaning is a kind of bending) and 'leaned' is located in the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for learned that I've seen before include "Having great knowledge" , "Picked up - well-read" , "Highbrow" , "Studied" , "Acquired and digested knowledge" .)
