Republican presidential hopeful Mitt Romney says he's all for immigration, as long as it's legal and policies don't reward those who are already here.
On Thursday night, Romney and his rivals discussed illegal immigration at the GOP debate. Romney says workers who have come to the U.S. illegally would have to leave the country but would be eligible to apply to return as long as they went to the back of the line.
Newt Gingrich says the nation has to be realistic in confronting the millions of workers without documentation. But Gingrich also says he would cut off funding for so-called sanctuary cities and would drop federal lawsuits against states with tough anti-immigration laws.
