We should be deeply concerned with Mueller’s unlimited reach and unvetted hires. The way Mueller has conducted and unilaterally expanded his investigation, the subordinates he has hired, the persistent leaks from his office, and his abuse of attorney-client privilege — would all suggest his preference for questionable tactics.

Mueller has demonstrated he is incapable of leading a focused, unbiased review of his initial assignment. His witch hunt must end.

If Robert Mueller truly cared for justice, he would voluntarily step aside from his post. However, he has repeatedly shown that he has no interest in ending his crusade. The credibility of the American justice system — and indeed, our representative republic — is at stake.
