Senator Pat Toomey (Pennsylvania) and Philadelphia District Attorney Seth Williams had this op-ed in the WSJ Monday on the controversial nomination of Debo Adegbile to head the DoJ's Civil Rights Division. 

It is not the fact that NAACP-LDF defended a murderer under Mr. Adegbile's watch that disqualifies him, but the manner in which they went about it.  And, no, the fact that he was not the lead attorney on the case does not matter.  It was done under his watch, and, given the high profile of the case, it is inconceivable that he did not know and approve of it.
