The troll is talking about deporting a rich and very visible Chinese dissident seeking asylum, because of fraud accusations against him.

It's not impossible for an asylum-seeker to be a criminal, and it is not implausible that a billionaire got that wealth via fraud. But we can't trust accusations against Chinese dissidents that come from China. China has used many dirty tricks against dissidents, even against people that merely get in its way, so we must expect anything that attacks a Chinese dissident to be a dirty trick.

One possible solution would be to give him asylum, then let China petition to extradite him. To succeed, China would have to satisfy a US court that there are grounds to do so.
