The main Republican presidential contenders each decried the shooting of Martin, a 17-year-old African-American, allegedly by a neighborhood watch member, and joined with President Obama and other Democrats in supporting a Department of Justice investigation into the incident. "What happened to Trayvon Martin is a tragedy. There needs to be a thorough investigation that reassures the public that justice is carried out with impartiality and integrity," Republican presidential frontrunner Mitt Romney said in a statement. Rick Santorum, Romney's main rival for the GOP nomination, added: "It's a horrible case, and it's chilling to hear what happened ... I think it's pretty clear the problems we're seeing in this case, and hopefully the state Attorney General and local community is reacting and responding, and hopefully this matter will be an example of what law enforcement has to do in a case like this."
