How does the U.S. Supreme Court handle reciprocal attorney discipline?

The U.S. Supreme Court handles reciprocal attorney discipline very badly. At least in my experience, it has been the practice of the Supreme Court, if an attorney is suspended, to disbar the attorney. Therefore, if a lawyer is suspended for two years and a member of the bar of the Supreme Court, a rule to show cause will be issued. The lawyer may or may not answer. But the end result will be the same, a disbarment.
