An anonymous Treasury Department employee has asked a federal judge in Northern California to block a government request for information from Google that could reveal his or her identity.

The Treasury Department’s Inspector General’s Office earlier this year subpoenaed Google for records related to two YouTube videos consisting primarily of text, which the anonymous employee claims to have posted. The videos assert that officials at the Office of Financial Research, or OFR, the Treasury unit created in the wake of the 2008 financial crisis to help forecast and anticipate financial storms, discriminated against minorities in hiring, pay and promotion, particularly African-Americans.
