Two petitions, one calling for the termination of Assistant US Attorney Stephen Heymann, and the other for a similar fate for US Attorney Carmen Ortiz, were filed here and collected enough signatures for an official administration response (prior to the recent increase to 100,000 signatures). However, neither of these petitions has been responded to. Here are links to the petitions:

A response to these petitions, which crossed the signature threshold in place at the time they were filed, should be posted by the Administration.
