In February 2007, Bloch was again accused of unfair supervisor practices when several of his staffers complained they felt coerced into not cooperating with the OPM probe. Bloch's deputy issued a memo urging OSC employees to only meet with probe investigaters in a certain conference room and to report their interactions to their supervisors. Employees reported other attempts to obstruct the investigation including "suggestions that all witnesses interviewed ... provide Bloch with affidavits describing what they had been asked and how they responded."
