House Republicans plan to privately question the deputy attorney general, Rod J. Rosenstein, about discussions last year where he suggested secretly taping President Trump to expose a chaotic White House and removing him from office under the 25th Amendment. House Democrats complained that they were left out of the planning and pledged to push to attend the meeting. Representative Jerrold Nadler of New York, the top Democrat on the House Judiciary Committee, said his Republican colleagues “cannot be left alone in a room” with Mr. Rosenstein.

The chaos, legislative fumbling, and legal jeopardy should not obscure the ways that the administration is remaking federal policy in consequential ways. With the Trump administration’s chaos sucking up all the attention, it’s been able to move forward on a range of its priorities, which tend to be more focused on regulatory matters anyway. It is remaking the justice system, rewriting environmental rules, overhauling public-lands administration, and greenlighting major infrastructure projects. It is appointing figures who will guarantee the triumph of its ideological vision for decades to come.
