Texas state Sen. Carlos Uresti “groomed” nearly $900,000 out of a former client and grieving mother by cultivating a sexual relationship with her, according to prosecutors in court on Monday.

The 54-year-old Uresti, who has also been accused by multiple women of sexual harassment during his time as a legislator, is on trial for 11 felony charges—including money laundering, wire fraud, and securities fraud—over his alleged part in a Ponzi scheme involving frac sand company FourWinds Logistics?. Uresti, who served as legal counsel for the now-defunct company, has repeatedly denied all of the charges.
