Rove to Dems: Stop Making Excuses and Face the 'Inconvenient Reality'

A Washington, D.C., pizza parlor became involved in the "fake news" debate after a man was inspired by an internet conspiracy theory to fire an assault weapon multiple times inside the restaurant.

Edgar Maddison Welch had reportedly read online that Comet Ping Pong was the site of a child sex trafficking ring run by prominent Democrats, including Hillary Clinton.

James Alefantis, owner of Comet Ping Pong, joined Megyn Kelly on "The Kelly File" tonight to speak out about "Pizzagate."

Alefantis revealed that he had been receiving bizarre, threatening messages on social media since the conspiracy theory about his business emerged online in early November.

He said those "built and built" for a month, until Welch actually came to the restaurant with an AR-15 on December 4.

"It's dangerous," Alefantis said of the trend of fake news. "What happens is, this person was inspired to drive across four state lines with an assault rifle and enter a family-friendly restaurant at 3 o'clock in the afternoon on a Sunday."

He said that this scary incident proves that fake news can have real consequences, so actions should be taken to prevent these types of conspiracy theories from taking hold.

"This could happen to anyone," Alefantis said. "It's not just us. It's any single person."
