Do a couple of google searches on Robert Diegelman.

It's interesting.

Acting assistant attorney general for administration at the INS?

Seems he works for the Justice Management Division of the Justice Department. What do they do?

Under the direction of the Assistant Attorney General for Administration, the Division provides assistance to senior management officials relating to basic Department policy for evaluation, budget and financial management, personnel management and training, equal opportunity programs, ethics training and advice, automatic data processing and telecommunications, security, records management, procurement, real property, and material management, and for all other matters pertaining to organization, management and administration.

So my take? This department is unrelated to INS...it's job is to take the heat for the mistakes of INS. (But maybe that's just me.)
