Jonathan Chait: “Amid this torrent of lies, the president had identified one important truth. There has in fact been a series of firings and demotions of law-enforcement officials. The casualties include FBI director James Comey, deputy director Andrew McCabe, general counsel James Baker, and, most recently, agent Peter Strzok. Robert Mueller is probing the circumstances surrounding Trump’s firing of Comey for a possible obstruction-of-justice charge. But for Trump, obstruction of justice is not so much a discrete act as a way of life.”

“The slowly unfolding purge, one of the most vivid expressions of Trump’s governing ethos, has served several purposes for the president. First, it has removed from direct authority a number of figures Trump suspects would fail to provide him the personal loyalty he demanded from Comey and expects from all officials in the federal government. Second, it supplies evidence for Trump’s claim that he is being hounded by trumped-up charges — just look at all the crooked officials who have been fired! Third, it intimidates remaining officials with the threat of firing and public humiliation if they take any actions contrary to Trump’s interests. Simply carrying out the law now requires a measure of personal bravery.”
