Male assistant with Nixon, say, pocketing cash to create scandal for Kennedy (14)

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

'male assistant with nixon say pocketing cash' is the wordplay.
I cannot really see how this works, but
'male' could be 'chap' (chap is a kind of male) and 'chap' is located in the answer.
'assistant' could be 'pa' (personal assistant) and 'pa' is present in the answer.
'nixon' could be 'dick' (as in Richard Nixon - 'Tricky Dick') and 'dick' is present in the answer.
'cash' could be 'quid' (I have seen 'British cash' mean 'quid' so perhaps 'cash' could also mean 'quid') and 'quid' is found in the answer.
No letters remain.
This explanation may well be incorrect...

'to' acts as a link.

Can you help me to learn more?
