Trump has no idea where those 545 separated parents are and didn’t answer @kwelkernbc’s question about reuniting them, as I told @maddow. His admin invited me and others to see separated kids while detained and they were anything but “well taken care of.”

Monday I spoke with a still-separated father and son. The young man is eight now, living in CA with relatives and hasn’t seen his dad in nearly three years. @AlOtroLado_Org trying to reunite them. Listen to audio which aired on @NicolleDWallace’s show.

Read this reporting, too, from @KQED's @MichelleEWiley and @adrianamorgao, as @JoyAnnReid mentioned tonight, detailing @JusticeInMotion's search for the "unreachable" parents. https://www.kqed.org/news/11831289/how-covid-19-has-impacted-the-search-for-separated-families

And watch this award-winning @VICE documentary from the inimitable @ahylton26 to see the struggle to find and reunite families the Trump administration lost track of after separation.

As I write in my book, I deserve no credit for uncovering the policy. I was an unlikely eyewitness. @JuliaEAinsley got Gen. Kelly to admit they were considering it. @lomikriel discovered the pilot for @HoustonChron. @itscaitlinhd got a secret list of separations for @nytimes.

And many, many others have been covering immigration policy for far longer, understanding far better than I did at the time how decades of punitive deterrence-based policies under Dems and GOP administration allowed Trump to separate thousands which, indeed, was unprecedented.

If Biden wins, it doesn't mean harsh immigration policies go away. What will he do about indefinite detention of families? Expulsions of thousands of kids without due process? Interior enforcement which also separates families? Questions he must answer.

Make no mistake: Trump lied tonight, and is responsible for, as I've said, "torture" in the words of @P4HR and "government sanctioned child abuse" according to @ColleenKraft who was then president of @AmerAcadPeds, of over 5,400 kids, according to @ACLU's count.
