Former House Speaker Newt Gingrich says he would allow illegal immigrants to earn U.S. citizenship if they serve America in uniform.

Gingrich said during Monday's GOP debate that if president he would veto a version of the proposed DREAM Act that would allow a path to citizenship for children who come to the United States with their undocumented parents if they complete college.

Gingrich says college graduation alone is not enough.

Gingrich says citizens of other countries already have the opportunity to earn U.S. citizenship by wearing a uniform. He says that children of undocumented immigrants too should have that option.

Rivals Mitt Romney and Rick Santorum say they would veto any version of the DREAM Act that gives citizenship for college graduates.
