DORAL, Fla. (AP) — Republican presidential candidate Mitt Romney is suggesting that the news media is responsible for tarnishing his party's reputation among immigrants.Addressing a Hispanic leadership conference near Miami, Romney said Republicans aren't against immigrants or immigration.

He also wants to create a hemispheric task force to focus on drugs and other threats from Latin America.He said America needs to work harder at selling democracy in the region.Newt Gingrich addressed the conference earlier Friday.
