Federal agents may have stopped a major terror attack on the U.S. Capitol.
Christopher Cornell, who also goes by the name Raheel Ubdayah, was arrested Wednesday by FBI agents for plotting an assault on Congress, ABC News reported.
The Cincinnati man was picked up after buying two assault rifles and 600 rounds of ammunition, sources told the network. Fox News is reporting the purchase was made from an undercover officer.
Cornell's plan was to enter the iconic building, detonate multiple pipe bombs and gun down anyone who got in his way, according to an affidavit obtained by ABC.
The Islamic State sympathizer was first discovered by federal agents after "voicing support for violent 'jihad,'" according to ABC.
Further investigation into the man's background revealed his horror plot and led both the FBI and Department of Homeland Security to issue a nationwide bulletin, according to the report.
"The alleged activities of Cornell highlight the continued interest of US-based violent extremists to support designated foreign terrorist organizations overseas, such as ISIL, by committing terrorist acts in the United States," the bulletin read, according to the network.
"Terrorist group members and supporters will almost certainly continue to use social media platforms to disseminate English language violent extremist messages."
Twitter accounts belonging to media and the U.S. government have notably been hacked by extremists in the past several days.
Those infiltrations were used to post anti-American messages and supposedly secret government documents.
