I see I'm an hour late to this story, as regards DU. A summary of the story from my Shoutbox posts:
Briefly, the dude was an SS labor camp guard, participated in a mass slaughter, and then lied his way into the US and naturalization.
Then in 2001 he admitted who he was. Bush(?) got him de-naturalized and a deportation order in place by 2004. But neither Bush nor Obama could persuade Germany to take him.
The dude was collecting welfare for 10 or more years after the deportation order was in place. Finally, Trump, who alienates allies got Germany to accept him and deported him.
It crosses too many narrative re Bush, Obama, ICE, and Trump for DUpipo to pretzellate it easily to fit all those narratives without sounding barking bat-shit crazy-mad. So they ignore it. Two days from now it will be "old news", and by this time next week DUpipo will a new bright & shiny Hate-Trump object, and it will be as if this never happened.
