"Support Turkey!" - American Senate's leader (5)

I believe the answer is:

truss

'support' is the definition.
(trussing is a kind of supporting)

'turkey american senate's leader' is the wordplay.
'turkey' becomes 'tr' (I've seen this in other clues).
'american' becomes 'us'.
'leader' indicates taking the first letters.
The initial letter of 'senates' is 's'.
'tr'+'us'+'s'='TRUSS'

(Other definitions for truss that I've seen before include "Bind - structural framework" , "Architectural corbel" , "Tie up; support" , "Support for body" , "Tie up tightly; frame" .)

I've seen this clue in The Independent.
