On Tuesday, federal prosecutors announced that the man behind the Comet Ping Pong shooting will be charged with interstate transportation of a firearm with intent to commit a crime, the AP reports.Edgar Maddison Welch turned himself into police on December 4 after storming into the DC pizzeria with a military-grade assault rifle to investigate an online conspiracy theory known as "Pizzagate."Since the WikiLeaks email hack of top Clinton aide John Podesta, fake news sites and chat forums have contributed to speculation that Comet Ping Pong was actually a front for a child sex ring associated with top Democrats. The 28-year-old reportedly told police that he drove six hours from his home in Salisbury, North Carolina, because "he had read online that the Comet restaurant was harboring child sex slaves and that he wanted to see for himself if they were there."He then fired his gun inside, managing not to injure anyone, before leaving "when he found no evidence that underage children were being harbored in the restaurant," according to police.The local charges against Welch have since been dropped, but he now could face a maximum prison sentence of ten years behind bars or have to pay a fine due to the federal charge. William Miller, a spokesperson for the US District Attorney's office in DC, told Politico that Welch's hearing could happen as soon as Tuesday afternoon.
