To fully understand the events of that day, it’s imperative to know what the Secret Service did under such unprecedented circumstances. And the need for this information has only been heightened in recent weeks by disturbing revelations about three specific issues agents and officials would have insights on:

— The communications the Secret Service had with Trump about the weapons his rallygoers possessed and Trump’s desire to remove the security magnetometers at the rally so more of his supporters could be allowed in.

— An alleged altercation that occurred in Trump’s motorcade between Trump and his staff after Trump was denied his request to be transported to the Capitol.

— Pence’s refusal to allow the Secret Service to whisk him away from the Capitol after the mob breached its doors. Pence’s aide Greg Jacob chillingly testified last month that Pence told Tim Giebels, his lead Secret Service agent, “I trust you, but you’re not the one behind the wheel.”
