U.S. Senators Katie Britt and Maggie Hassan, D-N.H., are raising concerns that convicted American Taliban fighter John Walker Lindh violated his parole by repeatedly meeting with a convicted ISIS supporter.

Lindh was sentenced to 20 years in prison for aiding the extremist group. Lindh was released in 2019, three years before his sentence was set to be completed.

Lindh, a native of California, was interrogated by CIA officer and Alabama native Johnny “Mike” Spann hours before Spann’s death in an Afghan fortress where prisoners of war were being held.

Spann is considered to be the first American to die in combat during the invasion of Afghanistan in 2001.

Spann’s family has previously told AL.com they hold Lindh responsible for Spann’s death at the hands of Taliban prisoners because Lindh did not warn the CIA officer about the planned uprising that cost him his life.

“He had a chance to say he was an American and save Mike’s life and other Americans lives. He did not do that,” Spann’s father, Johnny Spann, told AL.com in 2019.

“It’s no different than if he pulled the trigger.”

Hassan and Britt are expressing concern about reports that Lindh violated a condition of his parole by meeting multiple times with Ali Amin.

Prior to Lindh’s release, Hassan and then Sen. Richard Shelby said they were alarmed about Lindh’s early release.

“Mike Spann is an American hero who made the ultimate sacrifice for our country and who made our state proud through his exemplary service,’’ Britt said in a statement to AL.com. “His legacy lives on, and his family continues to be in our prayers.”

“John Walker Lindh never should have been released early to begin with,’’ Britt said. “He is a convicted terrorist who has worked against America’s interests and the safety of our homeland, and he continued to express his belief in and commitment to terrorist ideology while incarcerated.

“Now, the Department of Justice has new, urgent questions to answer regarding why he was not sent back to prison for allegedly violating his parole by meeting multiple times with convicted ISIS supporter Ali Amin,’’ she said. “While this case is grave in and of itself, I am also deeply concerned that it could represent a systemic shortcoming that threatens our national security.”

Britt and Hassan in a letter to Attorney General Merrick Garland wrote, “In 2019, your agencies indicated that more than 100 individuals convicted of terrorism-related crimes would be released from federal prisons by 2025. While Lindh is an example of just one terrorist offender’s reported parole violations, we are also concerned that this example could be indicative of a systemic national security gap and emerging threat.”

They continue, “In 2019, Senator Hassan and Senator Shelby wrote to your agencies to express public safety concerns ahead of Lindh’s imminent release. While we appreciate the information that your agencies provided us in response, given the new report of Lindh’s parole violations, we are concerned that compartmentalized information between Department of Justice agencies may have prevented authorities from taking appropriate action.”

In their letter, the senators request information on whether Lindh or other released terrorist have attempted to, or successfully contacted, other violent extremists.

They also ask what steps the Department of Justice and its agencies are taking to protect against threats from possible recidivist terrorists.

“Given the fact that multiple Department of Justice agencies and offices – the Federal Bureau of Investigation, the Bureau of Prisons, and the Department of Justice’s National Security Division – have critical roles with investigations and oversight of these national security threats, the Department of Justice has a responsibility to review the troubling public reports about Lindh’s parole violations and provide responses to our questions,’’ the letter states.

“Thank you for your prompt attention to this matter. We respectfully request that the information requested be provided to our offices by February 24, 2023.”
