Benjamin Crump talked about news that a website has raised more than $200,000 for George Zimmerman, the man who killed the Florida teenager.
Crump has called this revelation "a bombshell.'" Zimmerman was released from jail this week after posting bond.
His family had told the judge they have had trouble coming up with the money to free him. Crump says this raises questions about Zimmerman's credibility.
"Trayvon Martin is dead," Crump said. "We don't know his version of what happened. The only other witness now is George Zimmerman and it's his credibility. And if he'll lie about little things like money and bond hearings, we know he'll lie about big things dealing with whether he's going to be convicted of second-degree murder."
Zimmerman's lawyer said the failure to disclose the money was an oversight.
