'itinerant' is the definition.
(I've seen this before)

'reporter entertains wild party briefly' is the wordplay.
'reporter' becomes 'teller' (I can't justify this - if you can you should give a lot more credence to this answer).
'entertains' means one lot of letters goes inside another.
'wild party' becomes 'rave' (a dance party).
'briefly' means to remove the last letter.
'rave' with its final letter taken away is 'rav'.
'teller' going around 'rav' is 'TRAVELLER'.
