Robert Zimmerman Jr., the brother of the man who was found not guilty of killing Trayvon Martin last week, said Friday that he's happy President Obama addressed the underlying issues of the case in a statement.

"I'm glad he spoke out today," Zimmerman said on Fox News, adding that he's been waiting for the president to weigh in since the verdict was handed down Saturday night.

Zimmerman echoed Obama's argument that inequalities in society can contribute to different views of what happened the night his brother, George Zimmerman, killed Martin, and said the country needs to move beyond race in future scenarios like it.

"I think the president was speaking off the cuff, and I think he was very sincere in his remarks," Robert Zimmerman said, adding: "My concern is that ... we do everything we can for children who are having difficulties — and I really see eye to eye with the president on that — difficulties in life."

He also said he doesn't disagree with the Justice Department's continued investigation of Zimmerman and whether to bring civil rights charges, but said the decision shouldn't be made in response to public pressure.

"I'm not sure that necessarily an investigation is a bad thing," he said. "I'm a little bit concerned sometimes that our leaders are responding to pressure."
