Frustrated in his continuing attempt to bring down Malaysian Prime Minister Najib Tun Razak, former Prime Minister Mahathir Mohamad has turned his sights on a new and vulnerable target – the prime minister’s big-spending wife, Rosmah Mansor. “He is going to go after her with everything he’s got,” said a longtime political operative. “When [Mahathir] was trying to drive out [former Prime Minister Abdullah Ahmad Badawi] in 2009, he went after Dollah’s wife [Jeanne Abdullah]. He even criticized Dollah’s former wife after she had died. He will use any weapon he can get his hands on. He is not going to let up.”
