Texas death row inmate Robert Roberson sat praying in a cell Thursday night, just feet from the execution chamber where he was set to die by lethal injection for the “shaken baby” death of his toddler.

On Wednesday, the lawmakers voted to issue a subpoena for Roberson to testify before the House Committee on Criminal Jurisprudence. On Thursday, they secured an order from a Texas judge staying the execution and forbidding state officials from preventing Roberson from answering the subpoena.
