Trump's plan akin to sending political opponents to the gulag.

The Washington Post reports Trump openly mulled the possibility of off-siting U.S. citizens to foreign prisons saying, “We have some horrible criminals, American grown, born.” He added that he’s “all for” sending them to prisons in El Salvador, where he has already detained some Venezuelan migrants.

OP
If in fact he believes in deporting criminals, he should self deport himself to a prison in El Salvador.
