General, Italian American, one who holds broadcast (7)
I believe the answer is:
agrippa
'general italian' is the definition.
(Roman general)
I don't understand the remainder of the clue.
(Other definitions for agrippa that I've seen before include "Acts reported of this king" , "Marcus -, Roman fleet commander who defeated Cleopatra at Actium" , "Old general" , "Powerful Roman" , "Marcus --, Roman general, statesman and architect" .)
