John,

300 beasts on two planes is not a wide cast net. That should be a fairly easy sort-out.
I doubt that HSI sent any choir boys to CECOT.
I read weeks ago that Maduro would not take them back, so CECOT is a staging area until he does.
They could also deliver them to the Venezuela border and tell them to walk east.

Due Process is an issue, although I am not accustomed to liberals worrying about due process.
However Trump has declared TDA a terrorist organization.
The US declared a "war on terror" for years now.

Who know how it ends up, but even a guy on MSDNC suggested that Trump could prevail because of the various special powers that a president has.
MSDNC seems to be toning it down. I suspect that they realize that they have been lured into a no-win trap.
