Distort, as facts (4)
I believe the answer is:
skew
'distort as facts' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for skew that I've seen before include "Place obliquely" , "Make biased or distorted" , "Suddenly change direction or position" , "(Make) oblique, slanting" , "Place(d) obliquely" .)
