tripped and evaded numerous detections and alarms on the white house ground. to break it all down for you, it was just about one week ago, last friday. we understand the 26-year-old jonathan tran was detected somewhere on pennsylvania avenue, about six hours before this breach even happened. then around midnight we know that he climbed over a fence at the treasury, at the treasury building, which is immediately adjacent to the white house. he then tripped a sensor alarm. the problem here is even though the alarm was tripped and there was an investigation into it, he wasn't detected. he snuck behind one secret service post, moved closer to the white house and an officer did come to investigate, but this intruder crossed over east executive drive, jumped another white house gate, it was a guard post that is not routinely staffed. likely wasn't staffed that night. and we understand that he was on the ground of the white house
