AUSTIN, Texas — A Texas man whose execution was halted and then called to testify at the state Capitol did not show up Monday over growing pushback from state leaders who have blasted lawmakers' last-ditch tactics to subpoena Robert Roberson and spare his life for now.

His absence at a highly anticipated state House committee meeting was another twist in what has become one of Texas' most unusual and contested death row cases. A group of Republican and Democratic lawmakers have rushed to Roberson's defense, saying outdated science led to a jury convicting him of killing his 2-year-old daughter in 2002.

After they subpoenaed Roberson last week to buy him more time, the attorney general's office opposed efforts to bring him to the state Capitol and told the state's highest court that doing so would present “myriad security and logistical concerns.”

The delayed execution has opened a rift in Texas between legislators and state GOP leaders, including Republican Gov. Greg Abbott, who say the last-minute maneuver on Roberson's behalf crossed a line.

“If this committee wanted to take a heavy-handed approach, there are dramatic ways that we could enforce that subpoena,” Democratic state Rep. Joe Moody said. “But we didn’t issue the subpoena to create a constitutional crisis, and we aren’t interested in creating division between branches of government.”

Roberson had been set last Thursday to become the first person in the U.S. executed over a murder conviction connected to a diagnosis of shaken baby syndrome. He was taken to America's busiest death chamber and was waiting in a holding cell when the Texas Supreme Court abruptly halted plans to give him a lethal injection.

Moody, the chairman of a state House committee that led efforts to stop the execution, said discussions about having Roberson eventually testify were still ongoing.

The Texas Attorney General's Office had told lawmakers that Roberson would only appear by videoconference, which Moody said would be “poorly suited” for Roberson because he is autistic.

“That doesn’t mean Robert won’t testify at all,” said Moody, without saying when Roberson might testify or how.

Among those testifying Monday about Roberson’s case was daytime television psychologist “Dr. Phil” McGraw and best-selling author John Grisham. The veteran talk show host McGraw threw his full support behind Roberson, stating that there was not enough evidence to convict him of a crime.

“If you execute people when you now know better, you need to abolish the death penalty. If that's the standard by which you're gonna execute people, you've got a bad system,” McGraw said.

Roberson's claims of innocence are backed by a group of Republican and Democratic legislators who say he was convicted based on outdated science.

Roberson received the death penalty for the 2002 death of daughter Nikki Curtis in the East Texas city of Palestine. Prosecutors argued that the infant’s death was caused by serious head trauma from being violently shaken back and forth. Roberson’s attorneys say that the bruising on Curtis’ body was likely due to complications with severe pneumonia and not child abuse.

Once Roberson testifies to lawmakers, prosecutors could seek a new execution date at any time, according to Gretchen Sween, one of his attorneys.

Lawmakers had sought to have Roberson transported from death row to appear in person, raising the possibility of an extraordinary scene in the Texas Capitol. However, the state attorney general's office told the committee he would appear virtually.

Abbott's office said the Texas Supreme Court should toss out the subpoena, writing that the House committee has “stepped out of line” in their first public statement on the case.

Almost 90 lawmakers across party lines, medical experts and civil rights advocates had called on Abbott to stay his execution. Abbott has not commented on Roberson’s case and the Texas parole board rejected pleas to grant clemency.

Rebuffed by the courts and Texas’ parole board in their efforts to spare Roberson’s life, legislators last Thursday subpoenaed Roberson to testify. Lawmakers on the House committee have expressed frustration with Texas' junk science law, which they say has failed to work as intended, including in Roberson's case.

The 2013 law allows a person convicted of a crime to seek relief if the evidence used against them is no longer credible. At the time, it was hailed by the Legislature as a uniquely future-proof solution to wrongful convictions based on faulty science. But Roberson’s supporters say his case points to faults in the judicial system where the law has been weakened by deliberate misinterpretation from the state’s highest criminal court.

In the last 10 years, 74 applications have been filed and ruled on under the junk science law. A third of applications were submitted by people facing the death penalty. All of them were unsuccessful.

Anderson County District Attorney Allyson Mitchell, whose office prosecuted Roberson, has previously told the committee that a court hearing was held in 2022 in which Roberson’s attorneys presented their new evidence to a judge, who rejected their claims.
