After rival Rick Santorum dropped out of the primary, leaving Romney the presumptive Republican nominee, the former Massachusetts governor indicated he would review potential legislation from Florida Sen. Marco Rubio that would have allowed some young illegal immigrants a way to stay in the country.
At a Univision forum last month, Romney said: "I'm not going to be rounding people up and deporting them from the country. ... I will put in an immigration reform plan that solves this issue."
The Denver Post interview comes as Romney and Obama are fighting a heated battle for Colorado, whose significant Hispanic population could determine which candidate receives the state's nine electoral votes.
