Don Wolfensberger at The Hill:

Here is the expungement paradox. On the one hand, there is a close precedent involving the president and Congress in which action was taken by one house against a president in a previous Congress. [The 1834 “censure” of Andrew Jackson} That house voted to expunge a previous action from the official record, and that order was actually executed by the Clerk. On the other hand, that precedent is not settled parliamentary law, never having been challenged as to its force and effect. It is sci-fi fantasy to think you can turn back the clock, revisit a past event, and actually change the course of history. In congressional parlance such a resolution is called a “sense of Congress” expression — a rhetorical device that reflects majority sentiment at the time it is adopted.
