Really I guess you will site your source after making that claim.
So, I cited one of Karl Roves failure to appear (he has several) for Congressional subpoena.
Now, you make a claim and when asked to cite:
You need to cite it your own damn self. I hate god damn partisan hack democrats like you .
Is there a reason you feel like others should provide support for their claims but you are exempt from this expectation?
I'm still waiting for a response as to why you think the entire Bush White House was given "executive privilege" to ignore subpoenas and why you think the Obama White House would be expected to NOT follow suit and just tell congress to take their subpoenas and shove them.
