A tweet put out with rage almost creates White House scandal (9)
I believe the answer is:
watergate
'white house scandal' is the definition.
(1970s US political scandal)
'a tweet put out with rage almost' is the wordplay.
'put out with' indicates an anagram.
'almost' means to remove the last letter (most of the word but not all of it).
'rage' with its last letter taken off is 'rag'.
'a'+'tweet'='atweet'
'atweet' mixed up with 'rag' can make 'WATERGATE'.
'creates' is the link.
(Other definitions for watergate that I've seen before include "Means of access for a current" , "scandal" , "target for a 1972 break-in" , "Burgled hotel" .)
