'looks for credit' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'when being truthful' is the wordplay.
I cannot really understand how this works, but
'when' could be 'on' (I've seen this in other clues) and 'on' is present in the answer.
'being' could be 'scout' (scout is a kind of being) and 'scout' is present in the answer.
This explanation may well be incorrect...
