President Donald Trump suggested Thursday that the United States is preparing to take new action against alleged drug trafficking networks in Venezuela, telling service members during a Thanksgiving call that efforts for strikes on land will be starting “very soon.”

Axar.az informs, citing CNN, “In recent weeks, you’ve been working to deter Venezuelan drug traffickers, of which there are many. Of course, there aren’t too many coming in by sea anymore,” Trump told service members in the call.

“You probably noticed that people aren’t wanting to be delivering by sea, and we’ll be starting to stop them by land also,” the president continued. “The land is easier, but that’s going to start very soon.

“We warn them: Stop sending poison to our country,” Trump added.
