In addition to being a prolific blogger and columnist for USA Today, Instapundit Glenn Reynolds is a professor at the University of Tennessee law school. That role qualifies him to identify the Mueller work on the obstruction-of-justice issue as suffering from conflict-of-interest, based on Mueller's long-time friendship with the key witness, James Comey.
Mueller should resign, in Reynolds' opinion, but if he does not then what? Reynolds' solution which accounts for the political sensitivities involved: Attorney General Jeff Sessions should appoint a second special counsel to focus on the obstruction-of-justice issue, leaving Mueller to focus on the collusion-with-Russians issue.
