The Texas governor’s pardon of a former Army sergeant who fatally shot a Black Lives Matter demonstrator undermines the state’s legal system and constitution and should be reversed, a prosecutor said Tuesday.

Travis County District Attorney José Garza said he is filing request with the Court of Criminal Appeals — the state’s highest criminal court — to review the pardon issued by Republican Gov. Greg Abbott, which he said made a mockery of the legal system and put politics ahead of justice.

“We will continue to use the legal process to seek justice,” Garza said during a news conference in Austin.

Daniel Perry shot and killed Garrett Foster during a protest in downtown Austin in July 2020. Perry was convicted and sentenced to 25 years in prison in May 2023, prompting immediate calls for a pardon from conservative figures. Abbott issued the pardon last month and Perry was quickly released from prison.
