A bill anchor-man organised (US president) (7,7)
I believe the answer is:
abraham lincoln
'us president' is the definition.
(Abraham (Abe) Lincoln)
'a bill anchor-man organised' is the wordplay.
'organised' is an anagram indicator.
'bill'+'anchor'+'man'='billanchorman'
'billanchorman' with letters rearranged gives 'brahamlincoln'.
'a'+'brahamlincoln'='ABRAHAM LINCOLN'
(Other definitions for abraham lincoln that I've seen before include "president" , "fatally, he watched some play" , "Famous American" .)
