OKLAHOMA CITY >> A 23-year-old man was “out for blood” when he attempted to detonate what he believed was an explosives-laden van outside an Oklahoma bank in a plot similar to the deadly 1995 bombing of the Oklahoma City federal building, authorities said today.

During a meeting with undercover FBI agents in June, Jerry Drake Varnell of Sayre, Oklahoma, said he held “III% ideology” and wanted “to start the next revolution,” a reference to the “Three Percenters” patriot movement — begun in 2008, galvanized by President Barack Obama’s election — and that has rallied against gun control efforts and pledges resistance to the federal government over the infringement of constitutional rights.

Federal officials arrested Varnell early Saturday in connection with a plot to detonate a vehicle bomb in an alley adjacent to BancFirst in downtown Oklahoma City. Varnell is charged with attempting to use explosives to destroy a building in interstate commerce.

Varnell made an initial appearance before a federal judge this afternoon and remains in the custody of federal marshals. Court records do not indicate whether Varnell is represented by an attorney.

U.S. Sen. James Lankford of Oklahoma, a member of the Senate Homeland Security and Governmental Affairs Committee, said the allegations are a somber reminder that Americans must remain vigilant about home-grown extremism and radicalization in local communities.

On Saturday, a rally by white nationalists and others opposed to a plan to remove a statue of Confederate Gen. Robert E. Lee from a Charlottesville, Virginia, park turned violent and led to the death of a 32-year-old woman who was struck by a car allegedly driven by a man into a crowd of people protesting the rally. A Virginia State Police helicopter deployed in a large-scale police response to the violence then crashed into the woods outside of town and both troopers on board died.

A federal complaint filed on Sunday says a confidential informant told the FBI in December that Varnell wanted to blow up a building and “that Varnell was upset with the government and was seeking retaliation.”

Officials said Varnell initially wanted to blow up the Federal Reserve Building in Washington, D.C., with a device similar to one used in the 1995 Oklahoma City bombing that destroyed the Alfred P. Murrah Federal Building, killing 168 people and injuring hundreds more.

In a series of text messages with the FBI’s informant, Varnell “claimed to have a bunker for when the world (or United States) collapsed” and indicated he was trying to build a team, the complaint states.

“I’m out for blood,” the complaint quotes Varnell’s texts. “When militias start getting formed I’m going after government officials when I have a team.”

But an undercover FBI agent posed as someone who could help Varnell build a bomb and the device used was actually inert, authorities said. Varnell’s actions were monitored closely for months as the plot developed.

“There was never a concern that our community’s safety or security was at risk during this investigation,” said Kathryn Peterson, special agent in charge of the FBI in Oklahoma.

The undercover agent met face-to-face with him on June 1 to discuss obtaining materials for an ammonium nitrate and fuel oil bomb similar to the one used in the Oklahoma City bombing, the complaint states.

Varnell indicated at the meeting that he had previously made homemade explosives and that he “was of the same mind with people who wanted to use explosives and make a statement,” the complaint says.

“Something needs to be done,” Varnell said, but killing a lot of people was not a good idea, according to the complaint. During text conversations in July, Varnell stated he wanted to conduct the attack after closing hours to prevent casualties but conceded that some bank workers or custodians who were inside the building could be killed or injured in the blast, it says.

The complaint says Varnell helped assemble the device and load it into what he believed was a stolen van. Shortly after midnight on Saturday, Varnell drove the van by himself from a storage unit in El Reno, about 30 miles from the bank in Oklahoma City, and dialed a number on a cell telephone that he believed would trigger the explosion. The FBI and members of a Joint Terrorism Task Force arrested Varnell shortly before 1 a.m.

The complaint also states that Varnell prepared a statement to be posted on Facebook after the explosion which reads in part that the attack was “retaliation against the freedoms that have been taken away from the American people” and “an act done to show the government what the people think of its actions.”

Both of Oklahoma’s Republican U.S. senators said the alleged plot could have rivaled the devastation caused by the Oklahoma City bombing 22 years ago.

“It is chilling to think that a sympathizer of Timothy McVeigh would want to act on hate, as a tribute to the 1995 Oklahoma City bombing, the deadliest terrorist attack on American soil before September 11,” Lankford said.

Sen. Jim Inhofe said law enforcement authorities “successfully prevented a hateful act of domestic terrorism.”

If convicted, Varnell faces between five and 20 years in prison.
