In the waning days of Malaysia's recent election campaign, then-opposition leader Mahathir Mohamad was investigated under the country's anti-fake news law.

Had he been charged and convicted, he could have spent as much as six years in prison. Instead, Mahathir was elected prime minister with a pledge to repeal the law.

After his unexpected success, Mahathir initially seemed to back off his promise, while other members of his government have since sent different signals.
