Steward Health Care CEO Ralph de la Torre might be held in contempt of Congress for refusing a subpoena to testify. 

Senator Ed Markey says they are working on a bipartisan contempt citation against the leader of the bankrupt company. 

An attorney for de la Torre informed a Senate committee this week that he cannot testify because of ongoing bankruptcy proceedings. 

Steward is in the process of selling six of its eight Massachusetts hospitals, while two others in the state closed last weekend.
