Redaction slip here vhttp://judiciary.house.gov/Media/PDFS/DAG2539-2603.pdf pagen 31. This is in the second tranche of the April 27 document dump. The topic is districts with declines in fire arms prosecutions (one was Southern California that is Carol Lam's district). The DOJ tries to redact identifying information for non fired US attorneys, but they missed a bit

"The district of Delaware's report to the Attorney General indicates a well developed PSN program, but I am concerned about the nearly 30% decrease in prosecution numbers."

The US attorney in question would be Colm F Connolly who was an assistent AG under Clinton and seems to have a stellar record. No favoritism (probably just a small state and a meaningless fluctuation).

Nothing to see here. Move along.
