According to The Post, it is unusual for Secret Service agents to allow a subject to wait for a car to arrive, as Clinton did while standing on a curb on Sunday.
It's also unusual for the leader of the detail to leave the subject's side. In the video, detail leader Todd Madison was seen leaving Clinton's side to open the doors of the van.
The atypical behavior is likely due to the unexpectedly rushed exit, a former agent told The Post.
"Every once in a while, you have to call an audible," he said. "We follow a methodology, not a script."
The Post originally reported that the agents may have broken Secret Service protocol. However, an agency spokesman said in a statement that "at no time did any Secret Service personnel violate security protocols."
