No where I could find that where Trump says he wants to deport 800,000 Dreamers, only that he wants to end DACA so Congress can get off their bums and pass a law giving the Dreamers a path to citizenship that is quicker.
Starting in 2001 Congress has screwed around on immigration and nothing was ever passed even when the Demos had a majority and the POTUS. 
If you have a credible source please post it.
I posted a few liberal type publications where Trumps talks or says he wants to stop DACA but nothing where he said he wants to deport the Dreamers.  Some of the articles imply it or suggest certain talking points from the White House but not Trump.
