Unlike Mr. Mueller, whose mandate was largely focused on any links between the Trump campaign and the Russian government’s interference in the 2016 presidential election, the federal prosecutors in Manhattan take an expansive view of their jurisdiction. That authority has enabled them, along with F.B.I. agents, to scrutinize a broader orbit around the president, including his family business.
Mr. Trump told The New York Times in 2017 that investigations into his family’s finances, beyond any relationship to Russia, would cross a red line, and last year he privately asked the former acting attorney general, Matthew G. Whitaker, if someone he viewed as loyal could be put in charge of the investigations at the Manhattan office, The Times reported last month.
At this point, it is unclear whether anyone will be charged with a crime. Some of the investigations involve allegations that may be too old to be prosecuted. Yet taken together, the investigations show that the prosecutorial center of gravity has shifted from Mr. Mueller’s office in Washington to New York.
The precise number of federal investigations around the country that have grown out of the special counsel’s work remains unknown because such inquiries are conducted in secret. But the special counsel’s office farmed out strands of its inquiry to at least three other United States attorneys’ offices, including in Brooklyn, the District of Columbia and the Eastern District of Virginia.
Separately, state authorities in New York are pursuing several investigations focused on the president, his associates and his business. Those matters include a mortgage fraud case against Mr. Trump’s former campaign chairman, Paul J. Manafort, as well as civil inquiries into the Trump Organization’s insurance practices, real estate deals, and whether the family’s charitable foundation violated tax laws.
