President Obama said in an interview with Univision airing Tuesday that he "probably" cannot legalize illegal immigrants by executive order -- a decision he might be faced with if Congress fails to pass comprehensive immigration reform.

"Probably not," Obama said, according to a transcript. "I think that it is very important for us to recognize that the way to solve this problem has to be legislative. I can do some things and have done some things that make a difference in the lives of people by determining how our enforcement should focus."
