NYT:

The chairman of the House Judiciary Committee delivered a flurry of document demands to the executive branch and the broader Trump world on Monday that detailed the breadth of the Democrats’ investigation into possible obstruction of justice, corruption and abuse of power by President Trump and his administration….

The letters from Mr. Nadler, dated March 4, went to 81 agencies, individuals and other entities tied to the president, including the Trump Organization, the Trump campaign, the Trump Foundation, the presidential inaugural committee, the White House, the Justice Department, the F.B.I. and dozens of the president’s closest aides who counseled him as he launched attacks against federal investigations into him and his associates, the press, and the federal judiciary. The committee will also investigate accusations of corruption, including possible violations of campaign finance law, the Constitution’s ban on foreign emoluments and the use of office for personal gain.

Rep. Nadler’s press release, the letters, and the documents requests are here.
