From the February 13 Republican presidential debate on CBS:
KIMBERLEY STRASSEL (PANELIST): Senator Cruz, you have promised to deport illegal aliens. You have also promised to reverse President Obama's executive action that gives temporary amnesty to illegals that were brought here by their parent as children. As president, you would have the names and addresses of the some 800,000 of those that have registered under that action. Now, you have said that in this country we shouldn't go door to door looking for illegals, but in this case you would have a list. Would you use it?
