Two lawyers serving as “independent consultants” will review wrongful conviction claims against the U.S. attorney's office in Washington, the office announced on Monday.

Jeffrey Robinson, a senior counsel at Lewis Baach and former associate director-counsel for the NAACP Legal Defense and Educational Fund, and Kristine Hamann, a visiting fellow with the U.S. Department of Justice's Bureau of Justice Assistance, will work with the U.S. attorney's office's new conviction integrity unit.

The announcement came as federal prosecutors in Washington continued to grapple with fallout from a scandal involving FBI agent Matthew Lowry, who was accused of tampering with drug and firearm evidence. Prosecutors have already dismissed criminal cases that Lowry was involved in against more than two dozen defendants. Defense lawyers have questioned the reliability of the FBI's policies for handling and safeguarding evidence and suggested the controversy could extend to a broader array of cases.
