The FBI has foiled a 'jihadist plot to attack the US Capitol' with investigators alleging that Christopher Cornell, pictured above in mugshot from Butler County Jail, came to their attention after he tweeted support for violent jihadist groups such as ISIL/ISIS.
According to court documents, the Ohio man was arrested and charged on Wednesday in connection with a plot to attack the US Capitol with guns and bombs.
Christopher Cornell, 20, of Cincinnati researched the construction of pipe bombs, purchased a semi-automatic rifle and 600 rounds of ammunition and made plans to travel to Washington to carry out the plot, according to an FBI informant's legal testimony.
Court documents showed that Cornell indicated on Twitter that he supported the Islamic State in Iraq and the Levant (Isil) under the alias Raheel Mahrus Ubaydah.
According to the documents, in instant messages to the undercover FBI informant, Cornell indicated that while he did not have support to conduct an attack on behalf of any group, "we already got a thumbs up from the Brothers over there and Anwar al-Awlaki before his martyrdom and many others."
