First Assistant U.S. Attorney Michele Brown was among the guests at a small social gathering held last Sunday at the Mendham home of Republican gubernatorial candidate Christopher Christie, but her attendance at the event - which was not political event though many of the attendees were Republican County Chairmen, legislators and campaign staffers - did not violate any federal law or regulation. 

Brown was the Executive Assistant U.S. Attorney and Christie's counsel before Acting U.S. Attorney Ralph Marra, Jr. elevated her to his old job as the number two in command of the federal prosecutor's office.  A career prosecutor, she is a close personal friend of Christie and his wife, Mary Pat, and has been the U.S. Attorney's office for seventeen years.

With some obvious restrictions, Justice Department employees are allowed to associate with and support political campaigns, according to a website maintained by the U.S. Office of Special Counsel.  Sources say that while some of the talk at Christie's home turned to politics and his bid to unseat Governor Jon Corzine, Brown did not participate in those conversations.  There are no guidelines against maintaining personal friendships while working at the Department of Justice.
