On Friday, a “president” with no political experience brought on a communications director with no communications experience.

Trump tapped Anthony Scaramucci, a Wall Street snake investment huckster, to be the new communications director, a move that caused Press Secretary Sean Spicer, who The New York Times reported “vehemently disagreed with the appointment,” to resign.

So, let me get this straight: Spicer was just fine with regularly walking out to that podium to spew and spin Trump’s lies, but hiring “the Mooch,” as Scaramucci is known, was the back-breaker? O.K., whatever, Sean.

This illustrates best what is wrong with this communications shop, and by extension, this administration: No one is concerned with the truth; they are only concerned with their own trajectories.

Nothing about this White House communications department was ever about communicating. On the contrary, it has always been about deception, concealment and equivocation. Informing the public was never the mission. Flattering Trump was the mission. But in the end, Trump will never be satisfied, because successful communications for him is to get people to buy his pack of lies, and that isn’t really working the way it once did.

Nothing will change with the arrival of the Mooch Communications Office because nothing has changed about the kook in the Oval Office. (Some may find that descriptor harsh, but I find no appellation too coarse to express my outrage over Trump’s character, behavior and agenda. If anything, no word feels grave enough to properly express it.)

Trump is suffering horrendous approval ratings, an impotent legislative agenda and his irrepressible impulse to shove his foot in his mouth. There is no real way to better package this disaster.

For that reason, I found this shake-up far less interesting than the developments last week about the inexorably advancing Russia investigation.

Maybe it’s just me, but I’m not interested in palace intrigue; I’m interested in the increasing possibility of prison and maybe even impeachment.

Think about all that happened last week: Donald Trump Jr. and the former Trump campaign chairman Paul Manafort were invited to testify in open session before the Senate Judiciary Committee about that shady meeting they had in Trump Tower with a Russian lawyer. And Trump gave an astoundingly bizarre interview to The New York Times in which he publicly slammed his own attorney general, Jeff Sessions, for recusing himself from the Russia investigation and drew a “red line,” warning that Mueller should not investigate the Trump family’s business dealings.

Reuters reported: “The Russian lawyer who met Donald Trump Jr. after his father won the Republican nomination for the 2016 U.S. presidential election counted Russia’s F.S.B. security service among her clients for years, Russian court documents seen by Reuters show.”

The Times also reported: “Banking regulators are reviewing hundreds of millions of dollars in loans made to Mr. Trump’s businesses through Deutsche Bank’s private wealth management unit, which caters to an ultrarich clientele, according to three people briefed on the review who were not authorized to speak publicly.”

The Times report continued: “Separately, Deutsche Bank has been in contact with federal investigators about the Trump accounts, according to two people briefed on the matter. And the bank is expecting to eventually have to provide information to Robert S. Mueller III, the special counsel overseeing the federal investigation into the Trump campaign’s ties to Russia.”

Not only did NBC report that “Marc Kasowitz is no longer leading the president’s group of private lawyers,” Politico reported that Mark Corallo, spokesman for the Trump legal team, resigned because he “was concerned about whether he was being told the truth about various matters.”

If people on Trump’s legal payroll are worried that they aren’t being told the truth, how worried should the rest of us be? Very, I would venture.

Then there was the Washington Post report: “Some of President Trump’s lawyers are exploring ways to limit or undercut” Mueller’s Russia investigation, “building a case against what they allege are his conflicts of interest and discussing the president’s authority to grant pardons, according to people familiar with the effort.”

The Post continued: “Trump has asked his advisers about his power to pardon aides, family members and even himself in connection with the probe, according to one of those people.”

I understand the press giving a lot of attention to the drama of changing press people, but that doesn’t even register against the import of what’s happening on the Russia investigation front.

All those things that have never made sense — Trump’s warm-and-fuzzies for Vladimir Putin, the mass amnesia about meetings with Russians by people connected to the Trump campaign, Trump’s prickly protectiveness about releasing financial details and documents, including his tax returns — must be made to make sense.

Mueller will not be threatened, the investigation will not be closed or constricted and the truth will be known. Incriminating personal communications are often hard to find, but financial records are often also kept by third parties and tell their own story.

As they say, follow the money.
