Critics are raising concerns about President Obama's nominee for secretary of the Department of Labor.

Thomas Perez, who is currently the head of the Justice Department's Civil Rights Division, was nominated for the position Monday.

Republicans are concerned about a report showing Perez gave incomplete testimony to the U.S. Commission on Civil Rights. The commission was investigating voter intimidation by the New Black Panther Party.

Perez testified that Obama political appointees were not involved in the decision to drop the case against three of the four defendants from the New Black Panther Party.

But the Justice Department's inspector general said Perez's testimony was deficient.

"We found that Perez's testimony did not reflect the entire story regarding the involvement of political appointees," the report stated.

The New Black Panther case was launched in 2008 when the Justice Department under the Bush administration sued two members of the New Black Panther Party, the NBPP's national chairman and the group itself.

After Obama took office, the Justice Department fought to dismiss the suit against three of the four defendants.
