President Trump took a brief detour from his remarks about opioid abuse prevention and drug pricing to lament what he described as the rigged system that targeted him.

He appeared to go off script when he came across a line about pharmaceutical companies “rigging the system” when it comes to pricing drugs more cheaply overseas than they do domestically.

“Many drug companies are giving European countries a better deal than they give their own country, and that has to stop,” Trump said.

“At long last we’re stopping the drug companies in foreign countries from rigging the system,” he continued. “I know all about the rigging the system because I had the system rigged on me.”

“I think you know what I’m talking about,” he added, to some laughter from the conference audience.

The President joked that his remark would become a highlight from his speech at the Atlanta gathering, which had otherwise stayed largely on the topic of drugs.
