Adam Davidson writes that a Senate panel’s request for information from a Treasury enforcement unit suggests a broader scope to its investigation. The FinCEN request is particularly interesting because the unit enforces money-laundering laws and is familiar with Donald Trump’s holdings, specifically the Taj Mahal casino, in Atlantic City. Trump opened the Taj Mahal in 1990. He sold half of his shares in 2004, as part of a bankruptcy settlement, but remained a minority owner. In 2015, the Taj Mahal admitted to “willfully” violating the law by letting many suspicious transactions go unreported to the authorities, and agreed to pay a ten-million-dollar fine—one of the largest ever for a casino.

Donald J. Trump paid $750 in federal income taxes the year he won the presidency. In his first year in the White House, he paid another $750. He had paid no income taxes at all in 10 of the previous 15 years — largely because he reported losing much more money than he made.

A former Deutsche Bank executive who reviewed President Donald Trump's tax returns reportedly said it is "not normal" that the institution no longer holds copies of those records.Trump for many years relied on Deutsche Bank for loans to sustain his real estate business when many other institutions would not lend to him because of his rocky financial history.The president is accused by some, including his former attorney Michael Cohen, of manipulating the value of his assets to either secure finance or reduce his tax bill.
