Defense attorneys chipped away Monday at potentially damaging testimony by a former Dewey & LeBoeuf general counsel, casting her as an insider who failed to share material information with investors in a firm bond offering when she had the chance.

The witness, Janis Meyer, served as general counsel at predecessor firm Dewey Ballantine as well as at Dewey & LeBoeuf, continuing to work for the firm for several months as an adviser to Dewey & LeBoeuf after it filed for bankruptcy in May 2012.
