The media is reporting that President Donald Trump’s legal team is investigating possible conflicts of interest by former FBI Director Robert Mueller. Today I ran a column in USA Today on those conflicts of not just Mueller but Deputy Attorney General Rod Rosenstein. I have great respect for Mueller but I believe it was a mistake of Rosenstein to select him given his history with Comey and his reported interview with Trump for Comey’s job. Nevertheless, as I have stated since this story broke this morning, I am very concerned with any concerted effort to investigate the investigators. Such an approach is less evidence of a strategy as a spasm. Clearly, defense counsel has a right — if not an obligation — to raise any known conflicts of interest with the Justice Department. Yet, such investigations can easily get out of hand and can trip legal wires if aides are too aggressive in investigating the investigators.
