Austin real estate developer Nate Paul began serving a 10-day jail sentence for contempt of court Thursday night in connection with a civil lawsuit that is unrelated to his criminal indictment accusing him of financial crimes.

The embattled investor has been fighting the sentence but was ordered to report to jail in Austin related to a dispute with the Mitte Foundation.

Paul, an associate of Texas Attorney General Ken Paxton, will serve 10 days in the Travis County Jail starting on Nov. 15.
