The leader of the world's largest economy believes all drug dealers should face the death penalty, news website Axios reported late on Sunday.

President Donald Trump considers drug traffickers to be as bad as serial killers and would "love to have a law" that executes dealers in the U.S., unnamed sources told Axios.

While he admits that such a law would be impossible to pass, the head of state may support legislation that requires a five-year minimum sentence for dealers selling as little as two grams of fentanyl, Axios stated.

Use of the synthetic opiod, more potent than heroin, has been steadily climbing in North America, producing an increasing number of fatal overdoses.

The government must make drug dealers fear for their lives, Trump has told associates, pointing to Singapore and the Philippines — where offenders can face death — as examples.
