perhaps this additional info on the senator being removed fills some gaps;

Democrat Senator Alex Padilla claims he was in the federal building waiting for a scheduled briefing with federal officials and General Guillot, when he heard DHS Secretary Kristi Noem was giving a press briefing nearby.  Senator Padilla entered the room and attempted to rush toward Noem without announcing his intention; he was intercepted by security and forcibly removed from the room while he began saying who he was.

What is witnessed on the cameras is exactly what would happen to any random person who attempted to confront a cabinet secretary during press briefing. However, Padilla and his tribe are claiming victim status as an outcome of his attempted publicity stunt.......more..........
