I'm a little stuck... Click here to teach me more about this clue!

'read nothing that he felt could be trump's area of expertise?' is the definition.
The definition suggests an adjective which matches the answer.

'read nothing that he felt could be' is the wordplay.
'nothing' becomes 'o' (looks like zero - 0).
'could be' indicates an anagram.
'read'+'o'+'that'+'he'+'felt'='readothathefelt'
'readothathefelt' is an anagram of 'THE ART OF THE DEAL'.
