Maybe the less that’s known about this the better, since it could be intimidating, but it’s unlikely to be used for two years any way, and even when the Republicans had the power to use it before they couldn’t, but I think it’s relevant to discussions we sometimes have about the “political” nature of federal agency decisions.  This would be that on steroids.  I’ve excerpted much of this Washington Post article:

GOP revives rule allowing lawmakers to target federal agencies, staffers

The rules package House Republicans approved late Monday (January 9) includes a provision allowing lawmakers to reduce or eliminate federal agency programs and to slash the salaries of individual federal employees.

Called the Holman Rule, the measure was proposed in 1876 but was sparingly used until it was reinstated by Republicans in 2017 and then dropped by Democrats two years later. In theory, it could apply to any federal worker or agency — but for now the move is seen as mostly symbolic, as the Democratic Senate could block Republicans from using the provision.

The rule is named for a House member who proposed it nearly 150 years ago as an exception to the general practice of keeping policy decisions separate from spending decisions

One attempt … in 2018, would have reduced to $1 the pay of a federal employee in charge of an office that had been the subject of whistleblower complaints; opponents called the move an attempt to punish without due process one individual who was involved in a wide-ranging dispute.

Even if an attempt to use the rule is ultimately blocked, though, “It’s the potential use that makes it so concerning,” said Max Stier, president and CEO of the nonpartisan Partnership for Public Service. “If you’re a federal employee, this now becomes a risk that you have to think ‘I may get myself in hot water or have my salary dropped to zero or my job could get axed’” when making a professional decision.

“Symbols can cause harm. We need a workforce that is committed to the public good and feels safe to make that choice. That’s what’s at risk here,” he said.

Republicans have embraced the Holman Rule as part of the party’s aggressive stance toward the federal government, including President Donald Trump’s attempts to create new job classifications that would make it easier to fire government workers and his decision to move federal agencies like the Bureau of Land Management out of D.C.

During the House floor debate, Rep. Kat Cammack (R-Fla.), an ally of House Speaker Kevin McCarthy (R-Calif.), blasted federal officials as “unelected bureaucrats, the true, real swamp creatures here in D.C.,” saying they had “run roughshod over the American people without consequence.”

Democrats and union leaders, though, denounced the rule’s revival as an opening for the GOP to attack federal agencies and the people working in them for political reasons. Democrats warned that Republicans could abuse the power to lessen federal workers’ salaries or fire them outright — particularly at a time when the government is investigating former president Donald Trump.

Republican backers on Monday, though, said that reinstating the rule would provide an important check on the federal government.Rep. Chip Roy (R-Tex.) — a member of the conservative House Freedom Caucus — said the Holman Rule would “restore the people’s House” in the face of administrative action.

“I think it’s another intimidation tool for civil servants who are simply doing their job,” said Rep. Gerald E. Connolly (D-Va.) in an interview. “It is designed to provide a chill effect on the ability of civil servants to do their jobs and carry out enforcement regulations and compliance with the law.”

“The whole point of it is to use it recklessly. There’s no way to use it responsibly,” said the public policy director of the American Federation of Government Employees, Jacqueline Simon. “It goes around everything that protects the civil service from political corruption — not just federal employees but entire agencies.”
