CNN’s Chris Cuomo acknowledged that the DACA program has “been legally dubious” since its enactment during a debate Wednesday with Justice Department spokeswoman Sarah Isgur Flores.

“There’s no question it’s been legally dubious from jump,” Cuomo said at the end of their conversation. “Nobody’s going to argue with that in a very compelling fashion. At least not this morning, but it’s also about what are you going to do for these people. This is a moral argument, not just a legal one.”

The exchange happened on CNN‘s “New Day” after a conversation on the Trump administration’s decision to rescind DACA (Deferred Action for Childhood Arrivals), the 2012 Obama-era program that shielded young illegal immigrants who came to the U.S. with their families from deportation.

Isgur Flores pointed out Sen. Dianne Feinstein (D., Calif.) said DACA was on shaky legal ground the day before.
