The Justice Department is reviewing aspects of two legal cases filed by E. Jean Carroll. Carroll, an 82-year-old former magazine writer, accused Donald J. Trump of sexual assault. The New York Times disclosed the ongoing investigation.

The inquiry focuses on donations made by a nonprofit established by Reid Hoffman, a billionaire and co-founder of LinkedIn. Hoffman, known for criticizing Trump, helped cover some of Carroll’s legal expenses. Details about possible charges remain unclear.

Andrew S. Boutros, the U.S. attorney in Chicago, clarified on Thursday evening that no criminal investigation has been initiated against Carroll. His statement did not address Hoffman. On Friday, Hoffman responded publicly, stating that Trump is targeting Carroll and him for supporting her legal battle against Trump.

Carroll has chosen not to comment, as confirmed through a representative.

Potential Challenges for Prosecutors

For prosecutors, pursuing charges in this context would involve considerable challenges. The Justice Department’s investigation into Ms. Carroll could evolve, potentially leading to new charges amid ongoing conflicts with Trump’s adversaries.

Key Statements in Question

In April 2023, Trump’s legal team, post his presidency, alleged that Carroll had concealed financial backing from Hoffman for her case. This accusation was submitted to the judge before the first of two trials related to Carroll’s civil suits.
