I hadn't heard that, so I did a quick Google search. It came up with this. Appears to be true, but the candidate is running for a different seat in the state:

The family of Texas businessman and politician Donald Huffines owns the late Jeffrey Epstein’s Zorro Ranch in southern Santa Fe County, which was purchased in 2023 by a limited liability company created just a month before the purchase.

Huffines, a former GOP state senator from Dallas, is now running a high-profile campaign for comptroller — a statewide office in Texas overseeing state financial matters.
