One would be forgiven for thinking Tuesday’s Senate Judiciary Committee hearing on the expiring Deferred Action for Childhood Arrivals program brought good news for the prospects of its legislative replacement.

“First and foremost,” Iowa Sen. Chuck Grassley, the chairman of the committee, said in his opening remarks, “any potential deal on DACA has to include robust border security, and by that, I don’t mean a wall.”

This was the quote that garnered the most coverage and inspired some optimistic tea leaf reading. If congressional Republicans weren’t going to insist on a border wall as part of a deal to protect Dreamers, as per the “deal” Democratic leaders struck with President Trump last month, then a Dreamer-saving compromise would be much more assured.

But the wall isn’t shaping up to be the problem. The problem is what Grassley brought up a few seconds later.
