Gonzales gone & Rove gone. Was there a quid pro quo?

The timing of both Karl Rove leaving the White House and now today, Roberto Gonzales announcing his "resignation" is suspicious to me.

I bring forward another suspicious event which happened just 2-3 weeks ago and cause me to wonder what was going on. The evening before the summer recess was to start for Congress, the Senate was embroiled in late night voting on a number of issues. One which passed surprisingly, was the bill that gave the President more, rather than less, authority to expand the wiretapping and surveillance program which Senate Democrats had proclaimed is unConstitutional. Many on the Left have wondered how this could have happened.

My question is this. Was there a Quid Pro Quo with the President and the Administration which was agreed to that if they promised to get rid of Rove and Gonzales, the Democratic controlled Senate would pass the bill?
