Robert Zimmerman is continuing to make media rounds to defend his brother George who was recently acquitted of second-degree murder and manslaughter earlier this month in the fatal shooting of Trayvon Martin.

Robert Zimmerman has served as his family's spokesman, appearing on national television shows since the case first came to light in February 2012.

In an exclusive interview with TheBlaze, Robert said that his younger sibling has been depicted as a "mythological monster" and that he is "definitely not the same person" he was before the shooting.

"I still see sadness in his eyes [and] I still perceive a great measure of uncertainty when I look at him and his expression," Robert Zimmerman said. "I don't get the impression that he feels safe."

According to Robert, his brother has suffered from long-standing effects ever since he shot and killed 17-year-old Martin, who was unarmed at the time. He said George holds a "great deal of remorse" over needing to take someone's life to save his own -- a claim that has repeatedly been used in explaining the motive behind the shooting.

"He was definitely not the same person I had seen a few days before the incident," he said.

The issue of race has been a central theme in media narratives and the national conversation surrounding George Zimmerman's trial, with many believing Zimmerman racially profiled Martin. However, George Zimmerman has insisted that race was not a factor in his decision to stalk and confront Martin who was walking home from a convenience store to watch a basketball game with his family. 

Robert also discussed President Barack Obama's recent remarks about the Zimmerman case and race in America, when he memorably said Martin "could've been me 35 years ago."

"I do have concerns with the messaging coming from our leadership," he said. "I'm concerned sometimes the messaging is ambiguous. I think the American people need time to digest the verdict."

Robert said the president spoke from a "legitimate perspective" in sharing his views and experiences as a black American. However, while he noted the issues were pertinent to many other Americans, he said he believes the comments also included some problematic elements.

And while Robert said he believes the Justice Department is entirely within its rights to investigate the case, he is hopeful that the department will end up with what he called "an accurate portrayal" of his brother.
