I was checking the transcript from Hannity, and it looks like Sherrodโ€™s resignation came during his show on July 19:

This is a rush transcript from โ€œHannity,โ€ July 19, 2010. This copy may not be in its final form and may be updated.
SEAN HANNITY, HOST: And this is a Fox News alert. An Obama administration official resigned just a short time ago after she was caught on tape appearing to tell an audience that she had used her position to racially discriminate against white farmers.
Now the woman, Shirley Sherrod, was the Georgia state director at the Department of Agricultural. Now the presidentโ€™s Agricultural Secretary Tom Vilsack just released a statement saying the USDA has a zero tolerance policy against discrimination.

Can the Left please point me to the extensive coverage on Fox News, other than the one article they had up on their website, that supposedly forced Vilsackโ€™s hand in firing this woman? Brett Baier didnโ€™t cover the story, for example, and according to Mediaite, โ€œFox News did not cover the story during their news hours before Sherrodโ€™s resignation.โ€ In all likelihood, her firing was in the works long before Fox News even had a chance to get to its prime time commentary on the video.

One other thing from the transcript:

HANNITY: Well, Iโ€™ve tried to reach out to Ben Jealous. He has yet to return my phone call and heโ€™s invited on this program if he would like to discuss it. Iโ€™d like to have him on.

This is all part of Foxโ€™s evil snookering plan. They gave Jealous a chance to refute the charges, yet he declined.
