A sister, brother and niece of indicted U.S. Rep. William Jefferson pleaded not guilty in federal court to fraud charges seperate from the congressman’s case.

New Orleans tax assessor Betty Jefferson, her brother Mose Jefferson and her daughter Angela Coleman were arraigned Friday on charges they pocketed more than $600,000 in state and federal grant money earmarked for charitable and educational programs.

Another relative, Brenda Jefferson, pleaded guilty Wednesday to helping conceal the alleged fraud scheme and agreed to cooperate with investigators.

U.S. Magistrate Moore Friday set bond at $100,000 for Betty Jefferson and Coleman and $200,000 for Mose Jefferson.

New Orleans Democrat William Jefferson faces separate corruption charges and awaits a trial in Virginia.
