The attorney who successfully defended George Zimmerman in his murder trial is being investigated by the Florida Bar, a spokeswoman confirmed to TheBlaze Wednesday.

“The Florida Bar has one case pending at staff in regard to attorney Mark O’Mara’s representation of George Zimmerman,” Florida Bar spokeswoman Karen Kirksey said. “All other information is confidential at this time and that is the case with all open investigations.”

The exact nature of the complaint, or who filed it, was not made clear.
