No - there is no due process or criminal charges at play here. The government detained them per immigration law in order to deport them, for the sake of argument lawfully. The government arranged to repatriate them. Then in order to attempt to negotiate a business deal Donald Trump ordered them not repatriated, and instead to be continued to be held in US custody without trial, without criminal charges, and without even the suggestion that the purpose was to charge them criminally. Rather the explicit purpose was to attempt to negotiate a business deal where they would remain working in the US. Holding people in custody in order to negotiate a business deal is the definition of hostage taking.
