(AP Photo/Jacquelyn Martin, File) (Newser) – The FBI says a 20-year-old Ohio man planned to attack the US Capitol with pipe bombs and gunfire, reports CNN. Christopher Cornell of Green Township is charged with attempting to kill a US government official. It was another FBI sting, and authorities say the plan stood little chance of actually becoming reality. ABC News reports that an informant told the FBI months ago that Cornell was posting under an alias on Twitter and advocating terror attacks in America on behalf of the Islamic State. The FBI then had an undercover operative strike up a relationship. “I believe that we should just wage jihad under our own orders and plan attacks and everything,” Cornell wrote, according to the FBI. “I believe we should meet up and make our own group in alliance with the Islamic State here and plan operations ourselves." Authorities say Cornell was researching how to make bombs, and they arrested him today after he bought two semi-automatic rifles and ammo in Ohio.
