The strategy is: try to get an investigation into the White House going. If the Republicans refuse, accuse the Republicans of a "coverup".
...so the Bush administration "doesn't" participate in cover-ups? One of the first executive orders out of the Bush administration was to 'lock up' presidential papers and make them off limits to 'freedom of information act'. The (then) Democrat congress let it pass, too. Why would they want Clinton's laundry aired? Washington, they NAME is coverup.
I've heard the old Watergate mantra: "It's not the crime, it's the coverup" a few times in the last week. I expect to hear it a lot in the next few months.
