I don't believe this is a sign of a deepening crisis; the United States is facing an increasing heat of partisan politics, it does have a budget deficit, it does have a huge debt, but those are the problems that have long been there, and they are being resolved in a way, so I don't believe that potential change of one of the administration officials, is either a sign or a stimulus to the crisis deepening or becoming worse.
