Did Pelosi and Schumer intentionally conflate DACA with the DREAM Act at dinner in the Blue Room and try to roll the president into supporting more sweeping changes? Who knows?

Did the president negotiate immigration policy with Pelosi and Schumer without really knowing the details? Who knows?

But Trump never has sweated details in his business life. He’s never been intellectually sophisticated and he certainly hasn’t been a student of public policy. So I would wager that the president doesn’t know the difference between DACA and the DREAM Act, but possibly got an earful from immigration hardliners on his flight down to Florida.
