In a statement from NAACP President Ben Jealous, the civil rights group said they were “not done demanding justice for Trayvon Martin.”

“The most fundamental of civil rights—the right to life—was violated the night George Zimmerman stalked and then took the life of Trayvon Martin. We ask that the Department of Justice file civil rights charges against Mr. Zimmerman for this egregious violation,” said the group in a petition unveiled Saturday night. “Please address the travesties of the tragic death of Trayvon Martin by acting today.”

On CNN Sunday, civil rights leader Rev. Jesse Jackson also demanded that the Justice Department “intervene” and “take this to another level.”

Many Democratic lawmakers are also joining those calls, with Rep. Steve Cohen (D-Tenn.) tweeting a message from Jealous asking for the DOJ to act.
