Court filings by Manhattan District Attorney Cyrus Vance Jr. on Monday led to renewed speculation that prosecutors in New York have targeted President Donald Trump with a wider probe into possible fraud or other financial crimes than was previously known—demanding eight years of personal as well as business tax documents just weeks after the U.S. Supreme Court ruled a subpoena for such material must be honored.

According to the New York Times, the first news outlet to report the new developments:

The prosecutors did not directly identify the focus of their inquiry but said that "undisputed" news reports last year about Mr. Trump's business practices make it clear that the office had a legal basis for the subpoena.
The reports, including investigations into the president's wealth and an article on the congressional testimony of his former lawyer and fixer, Michael D. Cohen, said that the president may have illegally inflated his net worth and the value of his properties to lenders and insurers. Lawyers for Mr. Trump have said he did nothing wrong.
The clash over the subpoena comes less than a month after the Supreme Court, in a major ruling on the limits of presidential power, cleared the way for Mr. Vance's prosecutors to seek Mr. Trump's financial records.
