Federal prosecutors and defense lawyers for Greg Craig clashed in court this week as the two sides seek to shape the contours of his approaching trial, where the former Obama White House counsel intends to contest charges he misled the U.S. Justice Department about his work for Ukraine as a prominent partner at the firm Skadden, Arps, Slate, Meagher & Flom.

In court filings, Craig’s defense team at Zuckerman Spaeder have pushed to exclude evidence  they argue is irrelevant to charges that he deceived the Justice Department in 2013 as it scrutinized whether he should register as a foreign agent for his work for Ukraine.
