It's not my claim that it ends in June, MW. Sean Spicer said in a February White House Press Conference on DACA that the "thinking is to let is expire in June." The program started in June of 2012 with Janet Napolitano's Memorandum. Obama renewed it for 3 years in 2014, with an EO, so I guess that's why they think it expires in June.

I've posted all I know or am going to say about it.
