Robert Zimmerman says that his family has not spoken to his brother, George Zimmerman, since he was acquitted for the murder of Trayvon Martin because President Barack Obama's administration may be listening to their phone calls.


In an Tuesday interview on Fox News, Robert Zimmerman said that George Zimmerman's parents had not spoken to or seen their son since the verdict on Saturday night.

"We do have concerns and always have of having our phones tapped, having our phones, you know, listened to by the administration or whomever because George is now as we know continually the subject of ongoing investigation."

"So a lot of the things that we do are connecting in person, that's how we've managed to stay hidden for so long, that's kind of old school, but it works," Robert Zimmerman added. "I have not spoken to him directly for the same reason."
