Attorney General Eric Holder will address the NAACP, which is urging him to pursue civil rights charges against George Zimmerman for the death of Trayvon Martin, at the organization’s 104th convention Tuesday in Orlando, Fla.

The NAACP, which is holding its convention about 30 minutes from the Florida town where Zimmerman and Martin had their fatal encounter, has asked the Justice Department to consider charging Zimmerman with a hate crime. Holder will speak at 4:30, according to the Justice Department.

“Zimmerman acquitted on all charges,” the group tweeted. “We will update you as we work to pursue civil rights charges against Zimmerman through the DOJ.”

Benjamin Crump, the Martin family attorney, addressed the convention today.
