Federal prosecutors have agreed not to offer as evidence at Greg Craig's trial the settlement his former law firm, Skadden, Arps, Slate, Meagher & Flom, reached in January to resolve claims that it failed to disclose past work for the Russia-aligned government of Ukraine.

Craig, a former Skadden partner in Washington who earlier served as the top lawyer in the Obama White House, is charged in the U.S. District Court for the District of Columbia with misleading authorities about his preparation of a report on the prosecution of Yulia Tymoshenko, a former prime minister of Ukraine and political rival of the country's president at the time, Viktor Yanuovych. Craig, represented by a team from Zuckerman Spaeder, contends he was not required to disclose his work under the Foreign Agents Registration Act, an 80-year-old law requiring the disclosure of lobbying work for foreign governments and other overseas interests.

Craig has pleaded not guilty. His trial, which is expected to last two weeks, is set to begin Aug. 12.

In January, Skadden agreed to pay $4.6 million to resolve U.S. Justice Department claims that the law firm violated the Foreign Agents Registration Act, or FARA, for work it conducted for Ukraine beginning in 2012. Skadden retroactively registered as a foreign agent of the Ukrainian government. The settlement amount represented the firm's earnings from the Tymoshenko report.

“We believe that, based on this agreement, neither the Settlement Agreement nor the Skadden FARA filings will be raised by either party in any way during Mr. Craig's trial,” according to the filing submitted on Friday by Craig's lawyers and the prosecution team. “However, each party reserves the right to ask the court for permission to introduce this evidence in rebuttal and/or in response to any argument or evidence offered by the other party that makes it relevant to the jury's determination of the charges.”

The testimony agreement, which still requires the approval of Judge Amy Berman Jackson, includes a stipulation that the government will limit the scope of testimony for two unidentified witnesses.

Craig's defense team said it will not elicit testimony from one of those witnesses regarding communication with Craig after Jan. 16, 2014, and the government will not seek to cross-examine a witness about communication and events that occurred after Jan. 16, 2014.

The government said it won't introduce Skadden's retroactive registration as a foreign agent for Ukraine.

Sealed proceedings were held earlier in front of U.S. District Judge Beryl Howell in Washington over attorney-client privilege matters involving Craig. Jackson first noted those proceedings in an order last week. She had planned to review that litigation, but she said Friday that there is no need for her to do so at this time.
