Special counsel John Durham is asking a judge to examine potential conflicts of interest in Latham & Watkins's defense of former Perkins Coie partner Michael Sussmann. 

The issue stems from Latham's prior representation of Perkins Coie and another of its former partners, Marc Elias, on issues also related to Durham's probe that may be relevant in Sussmann's upcoming trial, according to a motion filed by Durham's prosecutors.
