Robert Gibbs gave the daily White House briefing. Questions were focused on Shirley Sherrod, the former Agriculture Department official who was fired when a video of her surfaced in the media. The video, originally posted on a conservative website, appeared to show Ms. Sherrod making racially insensitive comments. That interpretation proved to be false after the full video became available. Mr. Gibbs in his remarks said that President Obama has personally apologized to Ms. Sherrod.
