Charles Marino: Sloped roof security failure exposed ‘all the other cracks’ in the Secret Service

Former Secret Service Special Agent Charles Marino says the Secret Service’s failure to cover the gunman’s roof at former President Donald Trump’s Butler, Pennsylvania rally exposed “all the other flaws” in the agency’s security plan. "[The investigation] is going to be a huge systemic look at the Secret Service. Not just what happened that day, but really how the agency’s being run each and every day,” he says.
