There’s a flood of commentary on the Supremes’ decision legitimizing Trump’s Muslim travel ban. The most cogent, to me, is this one from Politico. We can’t rely on the Court to constrain Trump’s rogue use of presidential power, and even less so with Anthony Kennedy’s retirement and a further move on the Court to the hard right. If the Mueller investigation finds evidence of wrongdoing and Trump blows it off, we can’t look to the Supreme Court. The ball is back in the lap of Congress, with impeachment the only remedy.
