The Washington Post was the first to release the news that Special Counsel Robert Mueller is investigating Donald Trump for obstruction of justice, but the New York Times piece from later on Wednesday evening finishes on a note that’s likely behind the increase in orange ire.

A former senior official said Mr. Mueller’s investigation was looking at money laundering by Trump associates. The suspicion is that any cooperation with Russian officials would most likely have been done in exchange for some kind of financial payoff, and that there would have been an effort to hide the payoffs, most likely by routing them through offshore banking centers.

Looking into not just Trump’s finances, but those of Jared Kushner, Paul Manafort, Michael Flynn and others makes it all but certain that someone is going to find a friendly team of agents at their door. That is, if Trump allows Mueller to complete the investigation.

In fact, if Mueller is looking for money laundering, he really doesn’t need to look all that hard.

March 06, 2015 WASHINGTON, DC – The Financial Crimes Enforcement Network (FinCEN) today imposed a $10 million civil money penalty against Trump Taj Mahal Casino Resort (Trump Taj Mahal), for willful and repeated violations of the Bank Secrecy Act (BSA). […] Trump Taj Mahal admitted that it failed to implement and maintain an effective [Anti Money Laundering] program; failed to report suspicious transactions; failed to properly file required currency transaction reports; and failed to keep appropriate records as required by the BSA.

Looking into money laundering around Trump is like investigating moisture in the middle of the ocean.
