WASHINGTON (AP) — A judge has turned aside an administration effort to quash subpoenas to Agriculture Secretary Tom Vilsack, whose testimony is being sought in a lawsuit filed against the late blogger Andrew Breitbart.

Former Agriculture Department employee Shirley Sherrod sued Breitbart and his colleague Larry O’Connor after Breitbart posted an edited video of Sherrod, who is black, supposedly making racist remarks. Sherrod’s words were taken out of context.
