The Manhattan district attorney’s office appears to have entered the final stages of a criminal tax investigation into Donald J. Trump’s long-serving chief financial officer, Allen H. Weisselberg, setting up the possibility he could face charges this summer, according to people with knowledge of the matter.
In recent weeks, a grand jury has been hearing evidence about Mr. Weisselberg, who is facing intense scrutiny from prosecutors as they seek his cooperation with a broader investigation into Mr. Trump and the Trump Organization, the people with knowledge of the matter said. The prosecutors have obtained Mr. Weisselberg’s personal tax returns, the people said, providing the fullest picture yet of his finances.
