Federal judge delays President Obama's immigration action

There's trouble for the White House plan to help the millions who came to the U.S. illegally.

The initial phases of President Barack Obama's executive action on immigration were supposed to take effect as early as Wednesday.

But late Monday, a federal judge in Texas put that all on hold while 26 states challenge the orders.

Michael Olivas, professor of law at the University of Houston, explains what this means for the President's attempt to affect immigration reform.
