Robert Zimmerman Jr., the brother of Trayvon Martin killer George Zimmerman, says he's sorry for a series of racist Tweets about his brother's case.
"I made a mistake," Robert Zimmerman Jr. said during an appearance on CNN's Piers Morgan Live. "It unfortunately may not have helped George."
That's putting it mildly.
George Zimmerman is charged with second-degree murder for killing Martin, who was 17, in an altercation in a residential neighborhood in Sanford, Florida.
Prosecutors say the neighborhood watch captain racially profiled, pursued and shot the unarmed Martin as he returned from a convenience store.
That was February 2012. Fast forward to this week: Robert Zimmerman posted side-by-side photos of Trayvon Martin and a teenager arrested last week.
A teen who was arrested in the fatal shooting of a 13-month-old boy as his mother was pushing his stroller down the street in a coastal Georgia town.
The photos showed Martin and the teenager posing while making an obscene gesture. He wrote: "A picture is worth a thousand words ... any questions?"
In another tweet, Robert Zimmerman said, "Lib media shld ask if what these2 black teens did 2 a woman & baby is the reason ppl think blacks might B risky."
Pers Morgan, in his interview with Zimmerman, called the tweets about Martin and the other teenager "incendiary" and "bordering on outright racism."
"I understand this was controversial and I apologize," he said.
Mark O'Mara, George Zimmerman's lawyer, has also criticized Robert Zimmerman's tweets. George Zimmerman's murder trial is set for June.
