All this week, Donald Trump has raged against Democrats for subjecting him to congressional oversight—cruel and unusual treatment that he never once experienced during his first two years in office, when the House and Senate were controlled by Republicans who probably would have let him stash a body in their basements if it came to it. “An economic miracle is taking place in the United States—and the only thing that can stop it are foolish wars, politics, or ridiculous partisan investigations,“ he insisted, bizarrely, during Tuesday night’s State of the Union. “Congressman Adam Schiff . . . is going to be looking at every aspect of my life, both financial and personal, even though there is no reason to be doing so,” he ranted Thursday morning, adding, like a feral pigeon, “Never happened before! A continuation of Witch Hunt! PRESIDENTIAL HARASSMENT! It should never be allowed to happen again!”

Unfortunately for Trump, investigating whether or not the president of the United States is under the thumb of foreign governments or other individuals is a thing that is allowed, and Schiff and Co. do not appear to be intimidated by tweets, even in all caps. On Wednesday night, Representative Eric Swalwell, who serves on the House Intelligence Committee with Schiff, told Axios, “We are going to take an M.R.I. to any Russian financing that the Trump Organization and the president may have had,” adding, “We are not going to be so naïve to assume that he’s faithful to the Russians. There may have been other countries who have tried to financially influence him.” And in a sign that Schiff’s full-body cavity search will be deep and wide-reaching:

Schiff has hired one former career official at the National Security Council, Abigail Grace, who left the White House last year. She has a congressional e-mail address and is listed in a directory as working for the Intelligence Committee’s Democratic majority. A second career employee detailed to the Trump White House is also considering joining Schiff’s staff, according to people familiar with the matter. They didn’t identify the person.
