According to The Ulsterman Report and the confidential "White House Insider" source (who may or may not be on the level), it is only a matter of time before Holder submits his resignation:
Regarding Attorney General Eric Holder, Insider made our last communication very specific - we are reaching the-the moment of truth on Holder. Just today there are new reports indicating one of the killers of Border Agent Brian Terry – using guns provided them by the Obama administration, was in fact an FBI informant. According to these reports, both the FBI and ATF knew of the dangers posed to U.S. Border Agents – but did nothing to intervene. A known ambush against border agents that lead to the death of Brian Terry resulted. Is it any wonder the Obama Justice Department so recently sealed all records relating to the murder of Agent Terry? And can there be any remaining doubt a full-on cover-up by the Obama administration has been underway since the failed gunrunning program story broke?
