Ex-Clinton aide: 84 percent of Americans support turning undocumented immigrants over to authorities, by Tess Bonn.

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.
