Quote:Prominent Democratic pollster Mark Penn said on Thursday that a vast majority of Americans don’t really support so-called sanctuary cities that shield immigrants in the country illegally from deportation.

Penn, who served as chief strategist for Hillary Clinton's 2008 presidential campaign, revealed that 84 percent of Americans favor turning undocumented immigrants over to federal agents.

“I asked them, ‘Do you think notifying ICE [Immigration and Customs Enforcement] would in fact increase crime because it would inhibit people from reporting crimes or does it decrease crimes because it takes criminals off the street,’ and they overwhelming said ‘decrease,’ ” Penn told Hill.TV's “Rising.”
