(CNN) - Republican presidential candidates responded Monday to the apparent collapse of Libyan leader Moammar Gadhafi's government.
Monday marked "Day 2" in Tripoli for rebel forces as they made gains in the capital. While the whereabouts of Gadhafi were not known, three of his sons were in the custody of rebel forces. Here are the latest developments.
Former Massachusetts Gov. Mitt Romney: "The world is about to be rid of Muammar el-Qaddafi, the brutal tyrant who terrorized the Libyan people. It is my hope that Libya will now move toward a representative form of government that supports freedom, human rights, and the rule of law. As a first step, I call on this new government to arrest and extradite the mastermind behind the bombing of Pan Am 103, Abdelbaset Mohmed Ali al-Megrahi, so justice can finally be done."
Texas Gov. Rick Perry: "The crumbling of Muammar Ghadafi's reign, a violent, repressive dictatorship with a history of terrorism, is cause for cautious celebration. The lasting impact of events in Libya will depend on ensuring rebel factions form a unified, civil government that guarantees personal freedoms, and builds a new relationship with the West where we are allies instead of adversaries."
Former Utah Gov. and U.S. Ambassador to China Jon Huntsman: "The impending fall of Colonel Gaddafi is one chapter in the developing story of a nation in turmoil. Gaddafi has been a longtime opponent of freedom, and I am hopeful - as the whole world should be - that his defeat is a step toward openness, democracy and human rights for a people who greatly deserve it."
Former Sen. Rick Santorum of Pennsylvania: "Ridding the world of the likes of Gadhafi is a good thing, but this indecisive President had little to do with this triumph. The stated task from the very beginning for this administration was to determine whether the US can positively influence the direction of the successor government. As we have seen in Egypt, the euphoria of toppling a dictator does not always result in more security for us and our allies in the region."
Rep. Michele Bachmann of Minnesota: "I opposed U.S. military involvement in Libya and I am hopeful that our intervention there is about to end. I also hope the progress of events in Libya will ultimately lead to a government that honors the rule of law, respects the people of Libya and their yearning for freedom, and one that will be a good partner to the United States and the international community."
