A federal judge has disqualified Baker & Hostetler and a key partner, Carole Rendon, from defending one of the opioid manufacturers in the first bellwether trial over the addiction epidemic.

Rendon, a partner in Cleveland, represents Endo Pharmaceuticals Inc. but previously worked as a federal prosecutor in Ohio, including as U.S. attorney of the Northern District of Ohio from 2016 to 2017. During that time, Rendon was head of a heroin and opioid task force that included officials from Cleveland and Cuyahoga County. U.S. District Judge Dan Polster focused on that task force in his March 20 disqualification order.
