FBI Arrests Suspected Islamic State Supporter in Ohio Over Alleged Plot to Carry Out Violent 'Jihad' Attack on U.S. Capitol

CINCINNATI (TheBlaze/AP) -- A man who plotted to attack the U.S. Capitol and kill government officials inside it and spoke of his desire to support the Islamic State militant group was arrested on Wednesday, the FBI said.

A criminal complaint filed in U.S. District Court in Ohio charges Christopher Lee Cornell with attempting to kill officers and employees of the United States. Just a day earlier, authorities revealed another Ohio man had been charged with threatening to kill House Speaker John Boehner.

Cornell, also known as Raheel Mahrus Ubaydah, was arrested as he took control of a firearm during an undercover FBI operation in southwestern Ohio, the FBI said. The public was never in danger in the investigation, said John Barrios, acting special agent in charge of the FBI's Cincinnati division.

A phone message and an email were left Wednesday for attorney Karen Savir, a federal public defender listed in court records as Cornell's attorney. A working phone number could not be found for Cornell's family members.

The complaint alleges that an FBI informant began supplying agents with information about Cornell last year. The informant and Cornell, who's 20 and lives in Green Township, first began communicating through Twitter in August and then through an instant messaging platform separate from Twitter, according to the complaint.

"I believe we should meet up and make our own group in alliance with the Islamic State here and plan operations ourselves," Cornell wrote in an instant message, according to the court document.

The Islamic State militant organization, which broke with the al-Qaida network and took control of large parts of Iraq and Syria, has drawn jihadi fighters from across the Muslim world and Europe. It has been blamed for violence such as the beheadings of foreign captives including a former U.S. soldier turned aid worker and two American journalists.

Cornell and the informant met in person in October in Cincinnati and again in November, the complaint states. Cornell told the informant at the November meeting that he considered the members of Congress as enemies and that he intended to conduct an attack on the Capitol, according to the complaint. The document says Cornell discussed his plan for them to travel to Washington and conduct reconnaissance of the security of government buildings including the Capitol before executing "a plan of attack."

Cornell planned for the two to detonate pipe bombs at and near the Capitol and then shoot and kill employees and officials, and Cornell had saved money to fund the attack, according to the complaint.

Cornell was arrested after buying two semi-automatic rifles and about 600 rounds of ammunition, authorities said.

On Tuesday, authorities disclosed a Cincinnati-area bartender had been charged with threatening to kill Boehner at a country club near his home with a gun or a poisoned drink. Boehner, a Republican, returned to the Capitol on Wednesday without commenting to reporters. But a Boehner spokesman, Michael Steel, said, "Once again, the entire Congress owes a debt of gratitude to the FBI and all those who keep us safe."

In a joint bulletin, the FBI and Department of Homeland Security reportedly alerted law enforcement agencies across the U.S. about the serious threat posed by U.S.-based "violent extremists."

"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. Terrorist group members and supporters will almost certainly continue to use social media platforms to disseminate English language violent extremist messages," the bulletin reportedly stated.
