Another House Republican has signed on to a Democratic-backed immigration reform plan.

Rep. Ileana Ros-Lehtinen (R-Fla.) signed on as a co-sponsor to the proposal Tuesday morning. Her support comes after Rep. Jeff Denham (R-Calif.) signed on as a co-sponsor over the weekend.

"I know that some in the press have said immigration reform is dead, and I wanted to show a proof of life," Ros-Lehtinen told reporters Tuesday. "We're just trying to fix a broken system, and it's important to keep the discussions going."

Both GOP lawmakers represent districts with sizable Latino voting populations, especially Ros-Lehtinen who represents a part of the Miami area.
