Immigration and border security are now at the center of the GOP presidential race. Hot Air spoke with Gov. Mitt Romney about sanctuary cities, Rudy Giuliani’s response to his criticism of NYC’s illegal alien safe haven policy, homeland security, ID cards, CAIR, and civil liberties, among other related topics. We’d of course welcome the opportunity to hear from Giuliani about these issues. Thanks to the Romney campaign for taking the time to speak to Hot Air’s audience.
