Leader touring around Washington State (8)
I believe the answer is:
delaware
'state' is the definition.
(Delaware is an example)
'leader touring around washington' is the wordplay.
'touring' is an anagram indicator (touring can mean moving around).
'around' means one lot of letters goes inside another.
'washington' becomes 'wa'.
'leader' anagrammed gives 'delare'.
'delare' placed around 'wa' is 'DELAWARE'.
(Other definitions for delaware that I've seen before include "NE US state" , "One of the original 13 US states" , "US state and river" , "The Diamond State, capital Dover" , "American state, capital Dover" .)
