David Frum: “As president, Trump would have no power of his own to quash directly any of these proceedings. He would have to act through others. For example, the most nearly unilateral thing that Trump could try would be a presidential self-pardon. Is that legal? Trump has asserted that it is. Only the Supreme Court can deliver a final verdict, which presents a significant risk to Trump, because the Court might say no. Self-pardon defies the history and logic of the presidential-pardon power. Would a Supreme Court struggling with legitimacy issues of its own take such a serious risk with its reputation to protect Trump from justice?”
“Trump has one way he might avert the hazard of the Supreme Court ruling against him. He could order his attorney general to order the special counsel not to bring a case against his self-pardon, and then order the Department of Justice to argue in court that nobody but the special counsel has standing to bring a case.”
“Then things get complicated.”
