A Republican businesswoman who has expressed support for the QAnon conspiracy theory, Marjorie Taylor Greene, won her party's nomination Tuesday for a seat in the US Congress from Georgia, the New York Times said. Greene defeated John Cowan, a neurosurgeon, in a primary runoff. The winner will likely be elected in November in the conservative district. QAnon is a fringe belief propagated online that claims without evidence 'deep-state' traitors are plotting against President Donald Trump.
