I think that number was 611 as of January 14th but since then 105 children have been reunited with their families. 506 remaining so far. Of those, 322 likely had their parents already deported making it harder to find them.
Was doubting this administration would do anything about this--glad to be wrong. Hopefully we can get the rest reunited (and then let the horror stories really flow).
Whatever needs to happen to reunite these families in safe, effective and humane manner. Trump fucks just jailed them and couldn't unite them even under threat from judges.
