Trump: Venezuela's Maduro could face more charges

Maduro has pleaded not guilty to charges including "narco-terrorism" conspiracy, cocaine importation and possession of machine guns, after he was snatched by US forces in a nighttime raid in January.

"I would imagine there are other trials coming because they've really sued him just at a fraction of the kind of things that he's done," Trump told a cabinet meeting.

"Other cases are going to be brought, as you probably know," Trump said, giving no further details.

Thursday's hearing will likely see Maduro push for the dismissal of his case.
