Clinton said he didn't do it (6)
I believe the answer is:
inhale
'clinton said he didn't do it' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for inhale that I've seen before include "Draw breath" , "take the air" , "Whiff" , "Breathe in (gas, smoke)" , "Take smoke into the lungs" .)
