President Obama used part of his remarks in a reception Thursday honoring African American History month to remember Trayvon Martin, the Miami Gardens teenager killed three years ago in Sanford.
"Today, on the third anniversary of Trayvon Martin's death, showing all of our kids -- all of them -- every single day, that their lives matter -- that's part of our task," the president said, according to a White House transcript. "I want to thank Trayvon's parents for being here on what's a very difficult day for them."
Trayvon's parents were in the White House East Room for the event. The man who shot the unarmed 17-year-old, George Zimmerman, was acquitted by a jury. The U.S. Justice Department announced this week that it would not charge Zimmerman with a federal hate crime.
The boy's death set off a national debate on racial profiling and self-defense laws.
