Two Republican lawmakers on Wednesday called for a hearing to investigate why Gov. Terry McAuliffe and his administration will not release a report on the violent arrest of a black University of Virginia student by white state alcohol agents.

The March arrest of Martese Johnson by the enforcement arm of the Virginia Department of Alcoholic Beverage Control amplified a national debate over police treatment of minorities and revived scrutiny of the agency.

McAuliffe (D) immediately called for a review of the bloody incident, which was captured on video and widely shared on social media. By August, the ABC announced that state police had cleared the three agents of wrongdoing and that they were back on the job. But the report resulting from that review remains closed to public inspection.

Sen. Frank W. Wagner (R-Virginia Beach) and Del. C. Todd Gilbert (R-Shenandoah), who are chairmen of legislative committees that oversee ABC, said the report would help them evaluate whether to change the way the agency operates.

“If they did something wrong, we can fix it without throwing the baby out with the bath water,” Gilbert said. “I would not want to change the entire way they do business based on one incident or make a poor judgment, but without knowing exactly what happened, we’re sort of flying blind.”

Brian Moran, McAuliffe’s secretary of public safety and homeland security, said that because the report contains personnel information and because the state could face civil litigation over the incident, lawyers have advised him not to release it.

Moran added that the agents could release the report on their own, if they wish.

“From the beginning, the attorneys informed us that this is a personnel record, it’s in the officers’ file and therefore we are forbidden from releasing it. And we have acted accordingly,” he said.

Moran added that the report exonerates the ABC agents.

“What you can read from our conclusions, we have placed the officers back on duty. As a result of the report, we felt they could return to their regular duties,” he said.

Wagner, who faces a Democratic challenger this fall, said Moran told him he could have the report on Tuesday, but Moran denies saying that. Wagner followed up with a letter officially requesting the un-redacted report by the close of business Wednesday.

“I’m not going to be stonewalled. We’re an equal branch of government,” Wagner said in a phone interview. “Clearly the public has a right to know.”

In a letter responding to Wagner on Wednesday, Moran referred the senator to a video in which Charlottesville prosecutor Dave Chapman outlines the case based on a separate criminal investigation.

About a week after Johnson’s arrest, McAuliffe signed an executive order requiring that all ABC special agents be retrained in the use of force and in cultural diversity and interaction with young people. Last week, a panel McAuliffe created to study the incident released recommendations but did not call for changes in ABC’s law enforcement authority.

Johnson’s encounter with ABC agents began in the early morning of March 18 after he was turned away from an Irish bar adjacent to campus. It ended with him handcuffed on the ground and in need of 10 stitches on his head.

The arrest led to campus protests and highlighted the powers of Virginia’s ABC, which was sued after a 2013 incident in which its plainclothes agents confronted a 20-year-old white student in the parking lot of a Charlottesville supermarket.

Suspecting the student was carrying a case of beer, six agents closed in on her; one pulled a gun. All she had were bottles of LaCroix sparkling water.
