Is she being called a 'witch' ? The phrase 'witch hunt', of these procedings, certainly does not suggest she is one. But, no doubt, she has bewitching qualities.
The expression 'That's what they all say" comes to mind. Anyone and everyone in the public eye, whose activities have been the subject of wide publicity, makes the claim that are being victimised, it's a witch hunt, that they can never expect a fair trial, that the public have prejudged them on no true evidence and so on and so on. If anything, it may work against her. Protesting too much may be taken as indicating guilt.
