A federal judge Tuesday dismissed one of the two charges Greg Craig is facing in connection with his past work for Ukraine, handing the former law firm partner and Obama White House counsel a partial victory as he prepares to stand trial in Washington next week.

In a 57-page opinion, U.S. District Judge Amy Berman Jackson of the District of Columbia weighed Craig’s bid to dismantle charges he misled the Justice Department about a report he helped prepare for the Russia-backed government of Ukraine in 2012.  At that time, Craig was a partner at the law firm Skadden, Arps, Slate, Meagher & Flom, where he led a team that evaluated the Ukrainian government’s prosecution of Yulia Tymoshenko, a former prime minister and political rival of the country’s president at the time, Viktor Yanukovych.
