President Rodrigo Duterte has warned Congress not to toy with the Presidential Security Group (PSG), saying there will be a “crisis” if personnel of the unit will be forced to disclose details on their use of coronavirus disease 2019 (Covid-19) vaccine that was not registered with the Food and Drug Administration (FDA).

“I would like to call on Congress na hindi naman ako nakikiusap. Do not tinker with the PSG (I would like to call on Congress, I’m not appealing),” he said on Monday.
