extorts

I'm a little stuck... Click here to teach me more about this clue!

'wrings' is the definition.
('extort' can be a synonym of 'wring')

I cannot understand how the rest of the clue works.

(Other definitions for extorts that I've seen before include "Obtains by force or intimidation" , "Gains by threats" , "Gains by force" , "Threatens for money" , "Obtains by coercion" .)

I've seen this clue in The Globe and Mail.
