The Department of Justice announced Wednesday that a Cincinnati man has been arrested in connection to a plot to attack the U.S. Capitol and kill government officials.

The man purchased a firearm Wednesday, with the alleged intention to travel to Washington and kill federal employees. He was arrested thereafter.

"Christopher Lee Cornell, 20, of Green Township, OH, was charged in a criminal complaint with attempting to kill officers and employees of the United States and possession of a firearm in furtherance of a crime of violence," the Justice Department said in a statement.

The criminal complaint against Cornell includes messages he sent via instant message to an informant for the Federal Bureau of Investigation.

"I believe that we should wage jihad under our own orders and plan attacks and everything," Cornell wrote to the FBI informant. "We already got a thumbs up from the Brothers over there." Cornell also mentioned Anwar al-Awlaki, the al-Qaida-affiliated U.S. citizen who was killed in a drone strike in 2011.

During an in-person meeting between Cornell and the informant, Cornell "indicated that he considered the members of Congress as enemies and that he intended to conduct an attack on the U.S. Capitol in Washington, D.C.," the Justice Department complaint reads.

Here is the full criminal complaint:
