Did the national media bury the real reason presidential debate attendees were banned from using cell phone cameras after the event?

New York City’s WPIX aired a round up segment Monday morning on Sunday’s presidential debate, and ended it with the reporter and the morning show anchors taking photos with disposable cameras.

The report made note that electronic cameras were banned from the event at Washington University in St. Louis.

“Whoa, gah,” reporter Kirsten Cole said as the flash went off in her eyes. “This is why it was banned apparently.

“The Secret Service did not trust people to disable the flashes on they’re cameras, and they were afraid it would sort of inspire Hillary’s seizure disorder.”

The female anchor looked stunned.

“Wow, I did not know,” she said.

Debate attendees were ridiculed on Twitter for using the archaic technology.

While others pointed out all phones were banned:

Why has no other news outlet reported the information Cole did? Did she make it up or are other outlets covering it up?
