Bush blames snoopy senators for Miers' withdrawal

Rather than blaming himself for nominating someone so grossly unqualified that even conservatives didn't like her, Bush pointed his finger at the Senate Judiciary Committee: "It is clear that Senators would not be satisfied until they gained access to internal documents concerning advice provided during her tenure at the White House - disclosures that would undermine a President's ability to receive candid counsel."

The question is, what are those "internal documents" and why is Bush so intent on keeping them secret? Also, why did Bush capitalize "Senators" and "President"?
