Here are some of the recent scandals in Trumpland that deserve greater public scrutiny, or even congressional hearings and investigations.

MR. FIRST CLASS

Scott Pruitt, the champion of fossil fuel interests who is busily trying to destroy the Environmental Protection Agency, and his aides have made the ludicrous argument in recent days that he must fly first class because he is not safe in economy. This has elicited howls of laughter from aviation experts. Mr. Pruitt and his staff have racked up a tab totaling many thousands of dollars for domestic and international trips, including $1,641 for a brief flight from Washington to New York. Mr. Pruitt told The New Hampshire Union Leader that he has to travel in the front of the cabin because people in coach are mean to him. “We’ve reached the point where there’s not much civility in the marketplace, and it’s created, you know, it’s created some issues,” he said.

EUROPEAN IDYLL

In other travel news, the secretary of the Department of Veterans Affairs, David Shulkin, last week struggled to explain why the government spent $4,000 to fly his wife to Europe so she could accompany him for what was supposed to be a trip to attend a conference on veterans’ issues. Turns out, the happy couple spent nearly half the trip checking out sites like Amalienborg Palace in Copenhagen and Buckingham Palace in London. Oh, and they also improperly accepted free tickets to watch a tennis match at Wimbledon, according to the V.A.’s inspector general. Dr. Shulkin said he was repaying the Treasury for the cost of his wife’s ticket, though not before producing an unusual 28-page rebuttal to the inspector general’s report.

FAVORITISM AT THE F.C.C.

At the Federal Communications Commission, Chairman Ajit Pai is under fire from Democrats in Congress for relaxing rules that restrict how many local TV stations a business can own in one market, weeks before a large conservative broadcaster, Sinclair, announced it was acquiring more stations by buying Tribune Media. The commission denies any wrongdoing, but has refused to respond to members of Congress who have sought information about Mr. Pai’s contacts with Sinclair executives. The Times reported in August that the chairman and his staff met and corresponded with Sinclair several times. Earlier, The New York Post reported that Mr. Trump had met with Sinclair officials and discussed the F.C.C. rules. Clearly, there is nothing to see here.

FAMILIAL SUPPORT

It is hard to get good help when unemployment is at 4.1 percent. Perhaps that’s why Ben Carson, the secretary of the Department of Housing and Urban Development, saw fit to let his son, Ben Carson Jr., organize a “listening tour” for the secretary in Baltimore, despite warnings from department lawyers that doing so could violate ethics rules. One lawyer wrote in a memo that the son’s involvement could give “the appearance that the secretary may be using his position for his son’s private gain” because his son and his son’s wife might be doing or seeking business with people invited to attend events on the tour, according to The Washington Post. Mr. Carson says that he and his family did nothing wrong and that they were “under attack by the media.”
