Politico: “So far, all signs have pointed to Trump’s refusing the interview request, which would almost certainly force [Robert] Mueller to issue a grand jury subpoena to compel the president to talk. If this comes to pass, and the president refuses to comply with such a subpoena, the country will be in unchartered constitutional territory, and the courts will need to intervene. But history shows that when courts intervene because a president is trying to shield his own conduct, the deck is stacked against him. If Trump isn’t careful, he will end up shrinking his own authority—and diminishing the presidency for years to come.”
