Of course, they wrote this in 2016, and almost certainly did not mean it to be taken seriously now that the shoe is on the other foot. But it might be worth asking them.”

Plus: “A very similar letter was sent by 350 or so law professors to the Senate Judiciary Committee, concluding: ‘The Senate Judiciary Committee should hold a prompt and fair hearing and the full Senate should hold a timely vote on the president’s nominee.'”
