According to several media reports, the Secret Service will use bulletproof glass as part of a new plan to protect former President Donald Trump at his future outdoor events following his recent assassination attempt.

While this extra layer of security is typically used for sitting presidents and vice presidents, the agency has sought to tighten measures at Trump’s events after a gunman shot the former president at a rally in Butler, Pennsylvania, injuring his left ear. One rally-goer was killed in the attack and others were injured.

The armored glass panels, which are usually transported on special military aircraft during presidential visits, will be stationed in various areas of the country to be easily accessible at Trump’s events ahead of the November election, according to NBC News.

Authorities plan to shield Trump from three sides with panels, sources told ABC News, which first reported on the updated security plan.

A senior official described the entire effort to CNN as “a significant undertaking in logistical terms.”

The Secret Service has not commented on the reports, but the move was reportedly in the works before Kimberly Cheatle resigned from her post as Secret Service director a day after testifying before Congress about the shooting amid bipartisan calls for her resignation.

But installing bulletproof glass isn’t the only measure being taken to protect the former president. The agency also plans to deploy more personnel and use technology to mitigate security threats.

Trump has stopped holding outdoor rallies since the assassination, but has expressed his desire to resume such events and hold a new rally in Butler, his aides told The Washington Post.

The Secret Service had come under scrutiny following Trump’s shooting and acknowledged that the incident represented “a failure” for the agency.

“We want to deter people from even thinking about doing something like this again,” acting Secret Service Director Ronald Rowe said earlier this month.
