Embattled Steward Health Care CEO Ralph de la Torre to resign

The CEO of a hospital operator that filed for bankruptcy protection in May will step down after failing to testify before a U.S. Senate panel.

Steward Health Care CEO Ralph de la Torre has overseen a network of some 30 hospitals around the country. The Texas-based company's troubled recent history has drawn scrutiny from elected officials in New England, where some of its hospitals are located.

A spokesperson for de la Torre told CBS News in a statement Saturday that he "has amicably separated from Steward on mutually agreeable terms" and "will continue to be a tireless advocate for the improvement of reimbursement rates for the underprivileged patient population."
