Republican presidential candidate Mitt Romney is slamming Newt Gingrich on a slew of issues, labeling him a failed leader.
The two rivals are part of Monday night's presidential debate in Tampa, Fla.
Asked about the former House speaker's electability, Romney says Gingrich led Republicans to historic losses and that Gingrich resigned in disgrace. Romney says members of Gingrich's own team voted to reprimand him.
Romney is also highlighting Gingrich's ties to mortgage lender Freddie Mac. He says Gingrich was hired directly by a lobbyist for Freddie Mac and says it's a liability that would cost Republicans the general election.
In response, Gingrich says Romney is engaging in "disinformation" and he promises to dispute charges on his website. He says Romney is engaging in trivial politics.
All four of the Republican presidential candidates say they'd like to see a Cuba free of Castro's rule, though they differ on how they'd approach relations with Cuba.
Mitt Romney says it's important for the U.S. to stand with people who want freedom, including Cubans.
Newt Gingrich says he would use covert operations and other means to bring down Castro.
Rick Santorum says it's important for the U.S. to deal with Cuba but says he can't foresee a relationship before Fidel Castro and his brother are out of power.
For his part, Ron Paul says he would like to see the Cuban people celebrate their own freedom without any U.S. involvement.
The issue of Cuba looms large in Florida, where there are many Cuban expatriates.
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.
