Well, it is big news, the Shirley Sherrod/USDA/Vilsack/Tea Party/ Obama/Fox News.
Here's a link to Vilsack's press meeting: mms://ocbmtcwmp.usda.gov/content/secy/secy072110c.wmv
Key in this whole story is the concept of substantiate - neither side did - it was all about politics.
But, substantiate is closely rooted with substantial. Abraham Lincoln referred to the USDA as "the people's office." I cannot say any ag secretary, from either party, has done much to uphold Lincoln's vision.
Except for the pleasure it would bring to some, I think Vilsack should go. I worry, however, about who might replace him. If people are going to allow their buttons to be pushed what do we all deserve?
