When Former President and Republican Presidential nominee Donald Trump was shot at a rally in Butler on July 13, the security was questioned. The Secret Service may provide the answer because of their bulletproof glass that they are using to protect him, according to NBC News. The glass will be also well-traveled, as this form of advanced security will be transported by military aircraft. While this plan is still in the works, Former President Trump has not held an outdoor event since the assassination attempt happened.
