U.S. Defense Secretary Lloyd Austin approved a request for additional military support to the Secret Service to strengthen the agency's capacity to campaign for presidential and vice presidential candidates, the Pentagon and the Secret Service said Thursday in two separate statements.
Pentagon spokeswoman Sabrina Singh did not elaborate on the type of assistance that would be made available, but Austin said he had given instructions to plan and provide support to Secret Services at several locations throughout the campaign.
A Secret Service spokesman later said the agency had strengthened defense operations after the July 13 event in Pennsylvania, where Republican candidate Donald Trump, former U.S. President, was shot and survived an attempt to kill him.
"As part of these measures, the Department of Defense will provide the U.S. Secret Service with additional assistance in logistics, transportation and communications throughout the election campaign," the spokesman said.
Security measures at Trump's election rally in Butler, Pennsylvania, were raised amid concerns about how the suspect was able to get onto a rooftop from where he could directly see the podium where Trump was delivering the speech.
The Secret Service has expressed "embarrassment" over the failure to take security measures and the agency's director resigned after the event.
One participant in the rally was killed and two others were injured in the attack. The Federal Bureau of Investigation, the FBI, has not yet reached a conclusion on what prompted the suspect to shoot.
Republican presidential candidate Donald Trump and Democratic Vice President Kamala Harris are in close contests for the November 5 election.
