Her organization failed. As the head of the organization her job is to accept the failure and resign. Doesn’t matter the exact reason, she needs to take the fall. Trump never should have been cleared to speak if his safety wasn’t guaranteed. And I fucking hate the guy, but the secret service fucked up, a whole bunch of them should probably be fired, top brass first. Absolutely absurd to imagine they should keep their job after this. Normal people get fired for undercooking chicken, missing a day of work or delivering a package to the wrong place, what are we protecting here?
