An earlier news conference featured Hispanic activists, clergy and an immigration lawyer who noted President Obama is doing what Republican presidents Ronald Reagan and George H.W. Bush did before him.
"The sole difference between the action taken back then and the action right now is that the president is of the other party," said immigration lawyer Paul Zoltan.
"I think it's totally different," said Elizabeth Alvarez-Bingham, Vice Chair of the Dallas County GOP. "Presidents Reagan and Bush worked with Congress."
She says President Obama has gone beyond executive authority by creating a new category of immigrants
"Giving that status in blanket mass to basically everybody that applies for it is a totally different scenario than attempting to use your executive authority to sort of smooth the process to implement laws Congress has already passed, which is what Reagan and Bush did."
She expects the Supreme Court to have the final say in the case.
