WASHINGTON (Reuters) – U.S. intelligence officials have approved a new plan for Republican presidential candidate Donald Trump that calls for a continuation of outdoor rallies following the July assassination attempt, the Washington Post reported on Thursday.

The agency will use bulletproof glass and other technical security measures to protect Trump that are not normally made available to presidential candidates, the Washington Post quoted an unnamed Secret Service official as saying.

The former US President survived an assassination attempt on July 13 at a rally in Butler, Pennsylvania.

Security at that rally was under scrutiny as the shooting raised serious doubts about how the suspect was able to get to a nearby rooftop where he had a direct line of sight to Trump’s speech.

The Secret Service said it was “ashamed” of the security breach, and its chief resigned from his post following the attack.

The Secret Service did not immediately respond to a request for comment on The Washington Post report.

The shooting left one rally attendee dead and two others injured. FBI officials have not yet established a motive for the suspected gunman, 20-year-old Thomas Crooks, who was shot by a Secret Service agent after he opened fire.

After the attack, the Secret Service recommended that Trump avoid large outdoor events. Trump later said he would continue to attend outdoor rallies and that the Secret Service was “prepared to significantly increase its measures” to protect him.
