My fellow Americans, we are picking up some mighty big expenses for IRS employees.

A Fox News exclusive reveals:

The IRS spent more than $1.4 million on long-term travel for just 27 employees in fiscal 2015, including on high-end car services and luxury apartment and hotel stays, a Senate report has found — with one lawmaker blasting “woefully insufficient efforts” to reduce expenses at the agency.

The Senate Finance Committee report, obtained by FoxNews.com, found that while federal guidelines say employees must exercise the same care in incurring expenses as a “prudent person” traveling on personal business, IRS employees who traveled 125 business days or more racked up an average cost of over $52,000 a year.

The committee found more than half of the long-term travel time was spent in the Washington D.C., area. It found cases of five employees living in hotels, primarily in the capital, for months at a time without looking for lower-cost housing or having their per diem rates reduced as outlined in federal guidelines. 

Further, the committee found “the IRS does not routinely or actively seek to reduce per diem rates for employees on long-term travel.”

The generous per diem rate allows employees traveling to Washington to spend up to $7,099 a month on lodging alone, despite the committee seeing “virtually no circumstance” in which an employee would need to spend that much on a month-to-month basis.

And yet some employees pushed the limits on the taxpayers' dime.

I'd consider these expenses pushing it: $72, 544 for an IRS employee to stay a year in Washington hotels (among them the Ritz Carlton in Pentagon City), $4,950 a month for rental of a four-bedroom house in Arlington, Va., for a year, $4,605 for an apartment in Chicago for a year, along with such routine charges as $100 for black car service (I'd never even heard the term "black car service") from Manhattan to LaGuardia or a taxi to go grocery shopping and out to dinner.

The allowed per diem rate for travel to D.C. is up to $7,099 a month on lodging alone.

Senator Orrin Hatch responded:

Committee Chair Orrin Hatch, R-Utah, in a letter to IRS Commissioner John Koskinen, called the results of the report “frustrating,” noting what he called the “lack of effort” by employees to be prudent, which he said could be a direct violation of federal travel regulations.

“And yet, Committee staff saw example after example of routine Amtrak Acela trips, black car service, and luxury apartment rentals when reviewing IRS employee travel vouchers,” Hatch said. “Furthermore, the IRS made woefully insufficient efforts to reduce expenses in ways that would still allow employees to travel comfortably.”

The committee recommended the IRS significantly reduce per diem rates for long-term travel, as outlined by federal guidelines, and noted that the agency could see “significant cost savings among all employees who travel for significant amounts of time during the year” if it followed its own guidelines.

The IRS did not immediately return a request for comment from FoxNews.com.

And what are the odds that the IRS will likewise ignore the "frustrated" Senator Hatch?

The federal bureaucracy is honeycombed with people who spend our money lavishly on perks and feel safe and superior. It will take a herculean effort to clean out this Augean stable, but it is something that Donald Trump and his cabinet should make a do or die mission.

People who do things of this sort in the private economy would be fired, and firing must become an option in the fireproof federal government.

It does no good to be frustrated.

They don't care.
