Police officers are expressing outrage over President Obama's nominee for the head of the Department of Justice's Civil Rights Division.

Debo P. Adegbile has been selected to replace assistant attorney general Tom Perez, but critics are highlighting his defense of convicted Philadelphia cop killer Mumia Abu Jamal.

Adegbile represented Jamal when he worked as senior counsel for the NAACP Legal Defense and Educational Fund. Jamal was convicted of murdering police officer Daniel Faulkner in Dec. 1981.

Jamal's death sentence was overturned in 2012.

Peter Johnson Jr. broke down the controversy this morning on Fox and Friends, telling Steve Doocy that the Fraternal Order of Police has called it "unacceptable" for Adegbile to have represented Jamal.

Adegbile defended himself yesterday in a Senate confirmation hearing, but Johnson pointed out that the issue is not with whether Jamal was entitled to legal defense.

Rather, it's the question of which cases Adegbile will choose to take on in his "political" position within the Justice Department.
