When asked about it, Pawar said Khan had posed with stuffed carcasses, and there was nothing wrong in it.
Opposition Shiv Sena-BJP have targeted Khan over the pictures from her South Africa trip of six months ago.
Khan has denied that she herself had killed those animals.
Pawar said it was normal to find people posing with stuffed animals kept in hotels in foreign countries.
But to kill an animal and pose with the carcass was certainly not acceptable, he added.
