Ex-Judge Who Oversaw Review of Michael Cohen's Electronics to Do Same for Rudy Giuliani Case On 6/9/21 at 11:59 AM EDT The former federal judge who oversaw the review of Michael Cohen's electronics three years ago was formally appointed on Wednesday to do the same in the Rudy Giuliani case. Barbara Jones was appointed as "special master" by U.S. District Judge J. Paul Oetken, and will ensure attorney-client privilege is protected during the investigation into electronic devices owned by ex-President Donald Trump's former personal attorney after FBI raids in late April. Jones served as a Manhattan federal judge from 1995 to 2013. Investigators are probing Giuliani's interactions with Ukrainian figures to see if he violated a law governing lobbying on behalf of foreign countries or entities.
