• The New York Times has obtained 10 years of previously unrevealed figures from President Trump’s federal income tax returns. The tax numbers, covering 1985 through 1994, paint a bleak picture: Year after year, Mr. Trump appears to have lost more money than nearly any other individual American taxpayer, totaling over a billion dollars. Read the full investigation here, and five takeaways from the report here.

• Mr. Trump’s wholesale refusal to provide information to Congress threatens to upend the delicate balance that is the separation of powers outlined in the Constitution. His opposition to what he sees as partisan meddling could create a constitutional crisis — an impasse that the three branches of government cannot resolve.

• The White House stepped in on Tuesday to stop Donald F. McGahn II, the former White House counsel, from handing over documents subpoenaed by House investigators because Mr. Trump may want to assert executive privilege over them.
