Two Republican congressmen who are military veterans have introduced a bill requiring women to register for the draft.

Reps. Duncan Hunter, of California, and Ryan Zinke, of Montana, announced Thursday that the legislation is aimed at provoking a fuller discussion of the Pentagon's decision to open all combat jobs to women.

Hunter and Zinke say the decision ignores research from the Marine Corps and special operations forces. They also say the decision was made without considering whether women should be drafted and potentially serve on the front lines.

Hunter says it's unfortunate the Draft America's Daughters Act had to be introduced and he might even vote against his own bill.

Hunter served in the Marine Corps with tours in Iraq and Afghanistan. Zinke is a former Navy SEAL.
