Watch live: Witnesses testify on Robert Roberson case at Texas Capitol

The Texas Supreme Court has spared the life of death row inmate Robert Roberson, granting a rare stay of execution as prison officials were poised to administer his lethal injection. The Supreme Court's decision late Thursday came after days of legal wrangling and a furious effort by a bipartisan group of Texas lawmakers to stop Roberson's execution for the death of his 2-year-old daughter, Nikki, in 2002. Strong evidence suggests Roberson is innocent and was convicted based on shaken baby syndrome, which has been largely debunked.
