Senators of both parties should be reluctant to confirm nominee Thomas E. Perez as Labor secretary because he has provided inaccurate testimony under oath.

The explosive report by Department of Justice Inspector General Michael Horowitz details the existence of an open and toxic hostility inside the DOJ toward bringing voting rights cases to protect white victims of discrimination. When Perez testified before the Civil Rights Commission in May 2010, he denied he had ever heard of any such hostility. His testimony was false.
