"First, we call on you to end the Deferred Action for Childhood Arrivals (DACA) program created, without congressional support, by your Administration in June, 2012," the Republicans wrote.

Issa and his colleagues said Obama "must make an explicit public commitment that you will not support legislation that extends legal status to newly arriving illegal aliens no matter the age."
They also called on him to abandon his review of deportation policies aimed at finding ways to ease up on unauthorized immigrants who don't pose a security threat, saying he should make it clear that he'll provide "no special treatment for any illegal alien."
The letter comes two days after Obama announced that Speaker John Boehner (R-OH) told him immigration legislation won't come up in the House this year, and so he'll explore legal options to act administratively to fix the problems with the system.
