Dine out with Trump's vice-president, concealing desire for lack of bias (12)
I believe the answer is:
independence
'for lack of bias' is the definition.
(I've seen this before)
'dine out with trump's vice-president concealing' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'with' says to put letters next to each other.
'trump's' becomes 'end' (I can't justify this - if you can you should give a lot more credence to this answer).
'vice-president' becomes 'Pence' (Mike Pence).
'concealing' is an insertion indicator.
'end' put within 'pence' is 'pendence'.
'dine' is an anagram of 'inde'.
'inde'+'pendence'='INDEPENDENCE'
'desire' is the link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for independence that I've seen before include "Self-reliance" , "Autonomy" , "Freedom from outside control" , "State of relying only on oneself" , "Freedom from another's authority" .)
