We have seen repeated instances where President Donald Trump has stepped on the narrative of his defenders with a single misplaced tweet — often giving opponents precisely what they have been alleging. This weekend is another such example with a tweet saying ominously the House Intelligence Committee Chair Adam Schiff has not paid the price yet” for his role in Trump’s impeachment. The tweet sounded not only threatening but was immediately raised by Democrats as supporting what Schiff said in his closing argument about senators fearing retribution from Trump. One can easily view the tweet at a statement about political accountability, but the insistence on attacking Schiff personally is both improper and counter-productive. Trump was impeached by the House, not Schiff. He is fulfilling a duty under the Constitution. Some of us have criticized his representations, but alluding to personal costs for the House managers is wildly inappropriate in the middle of a Senate trial.
