President Barack Obama weighed in on a growing controversy over the February shooting death of an unarmed black Florida teenager Friday, as students in several South Florida high schools walked out of class to protest the killing and the investigation.
Martin, 17, was unarmed when he was shot and killed in Sanford, Florida, by a neighborhood watch volunteer while walking home from a convenience store on February 26, according to police.
George Zimmerman, who police said was the man who killed Martin, claimed he did so in self-defense. Zimmerman, whose family says he is Hispanic, has not been arrested or charged in the killing of the teenager, sparking a national debate over Florida's "stand your ground" deadly force law amid concerns about racial profiling. A grand jury will convene April 10 to look into the case.
Here is a roundup of Friday's developments in the controversy:
[Updated at 5:34 p.m. ET] Martin's parents, Tracy Martin and Sybrina Fulton, said in a statement that it was "humbling that President Obama took time from his busy scheduled to talk about Trayvon."
"The president's personal comments touch us deeply and made us wonder: If his son looked like Trayvon and wore a hoodie, would he be suspicious too?"
Martin was wearing a hoodie, or hooded sweatshirt, the day he died.
White House spokesman Jay Carney said no particular development prompted Obama to speak out. He said the president had been monitoring the situation and was prepared to answer a question if he received one.
[Updated at 5:11 p.m. ET] On the day President Obama talked publicly about the case, GOP presidential candidates also spoke up on Friday.
"There needs to be a thorough investigation that reassures the public that justice is carried out with impartiality and integrity," Mitt Romney said.
GOP rival Newt Gingrich said that while he believes in the right to self-defense, it appeared Zimmerman was "overreaching."
"The question here is: Was this guy attacked or was he the attacker? And that is what the grand jury will lead to. I mean if they decide he was the attacker, I suspect they'll indict him," Gingrich said.
And Rick Santorum told reporters on Friday that Zimmerman's actions looked starkly different from those protected by "stand your ground" laws.
"It's horrible case. I mean it's chilling to hear what happened. And of course the fact that law enforcement didn't immediately go after and prosecute this case is another chilling example of horrible decisions made in this process," Santorum said.
[Updated at 3:39 p.m. ET] The state prosecutor investigating Martin's death said her team is traveling to Sanford with a "blank slate."
State Attorney Angela B. Corey's team was scheduled to arrive Friday and begin seeking facts in the case. She replaces State Attorney Norman Wolfinger, whose district includes Sanford. Wolfinger requested that someone else be assigned, saying in a letter to the Florida governor: "This request is being made in light of the public good with the intent of toning down the rhetoric and preserving the integrity of this investigation."
Corey said Friday that she was not sure if a grand jury scheduled to begin meeting April 10 would be needed. She said her office has the power to charge Zimmerman, clear him or send the case to the grand jury.
[Updated at 1:50 p.m. ET] Officials with Miami-Dade County Public Schools have issued a statement urging students to respect the wishes of Martin's mother, who they say called them yesterday to "voice her disapproval of student walkouts and to encourage students to instead sign petitions, attend organized rallies and pray."
“While we respect the expression of emotion by our students, we ask that they remain focused on their education,” district school Superintendent Alberto M. Carvalho said. “Our most important mission is to provide a safe learning environment for students, and so we are asking them to respect the wishes of Trayvon’s mother by celebrating his memory not through walkouts, but through reflection and civic participation.”
Students in South Florida walked out of a number of high schools Thursday and Friday to protest Martin's death.
[Updated at 12:54 p.m. ET] Students from at least 10 South Florida high schools have staged walkouts to protest Martin's death, CNN affiliate WSVN reported.
Video from a WSVN helicopter showed students gathered on the Southridge Senior High School football field near Miami, standing in a formation that, when viewed from above, formed the letters "T" and "M" – Trayvon Martin's initials.
At Miami Edison High School on Friday morning, more than 900 students gathered at the school's track to demonstrate for an hour, CNN affiliate WPLG reported.
High school students aren't the only ones planning protests. In Dallas, people at Paul Quinn College planned to protest Martin's death Friday, CNN affiliate KTVT reported.
On Monday, people in Sanford, the Florida city of 50,000 where the shooting happened, plan to march to the site of a city commissioners' meeting, said Valerie Houston, pastor of Allen Baptist Church.
Also on Monday, students and civil rights leaders in Atlanta plan to march to the state Capitol to protest a Georgia state law similar to Florida's "stand your ground" statute, which doesn't require people to retreat from potential danger in public places and instead allows them to meet "force with force" if they believe there is danger of serious harm to themselves or someone else.
[Updated at 10:35 a.m. ET] Obama called the February killing of Florida teenager Trayvon Martin a "tragedy" on Friday.
"I can only imagine what these parents are going through. When I think about this boy, I think about my own kids," Obama said to reporters Friday morning. "I think every parent in America should be able to understand why it is absolutely imperative that we investigate every aspect of this."
Obama said Martin's death particularly resonated with him as an African-American parent.
"If I had a son, he'd look like Trayvon," Obama said in brief remarks outside the White House.
Obama's comments came during a news conference to announce that he would nominate Dartmouth College's president, Dr. Jim Yong Kim, to be the next president of the World Bank.FULL STORY
