Bongino - that roof was supposed to be a police post

NEW: Dan Bongino says an "unimpeachable source" tells him that someone was supposed to be on the roof where Thomas Crooks shot from but "didn't show up."

Bongino also claimed that the Biden admin is telling the USSS director to keep her mouth shut if she wants to keep her job.

"According to my source, that roof was supposed to be a police post... [there] was so supposed to be someone there."
