Jerry Drake Varnell was arrested in connection with a plot to detonate a vehicle bomb in downtown Oklahoma City. A 23-year-old man who said he hated the U.S. government has been arrested by the FBI for allegedly trying to blow up an Oklahoma City bank with what he thought was a 1,000-pound bomb in a truck.According to a&nbsp;criminal complaint, Jerry Drake Varnell&nbsp;wanted to start a militia group and admired Timothy McVeigh, the domestic terrorist who was convicted and executed for setting off a massive truck bomb&nbsp;outside a federal building in Oklahoma City in April 1995.Varnell thought he was dealing with two fellow sympathizers in the anti-government movement but they were a confidential informant and an undercover FBI agent working in a sting operation, according to the complaint.Varnell, who lives with his parents, was initially charged on Sunday with&nbsp;attempting to use explosives to destroy a building in interstate commerce. If convicted, he would face a mandatory minimum sentence of five years. He was to be arraigned late Monday.The FBI complaint said Varnell&nbsp;initially said he was interested in targeting the Federal Reserve Bank building in Washington, D.C.&ldquo;I&rsquo;m out for blood,&rdquo; Varnell wrote to the informant, according to the complaint, saying he wanted to take some action that would &ldquo;somehow cripple the government.&rdquo;Varnell said he had &ldquo;III percent ideology,&rdquo; a reference to a militia group called the Three Percenters, which&nbsp;believes the federal government is violating the U.S. Constitution, the complaint says.Raul Bujanda, the&nbsp;FBI agent in charge of the investigation, said there was no apparent link between Varnell&nbsp;and Saturday's violence by neo-Nazis, white supremacists and other far-right&nbsp;extremists in Charlottesville, Va.Bujanda said Varnell&nbsp;was not a member of any militia group, according to video of a press conference posted on NewsOK.Com.The FBI has been monitoring Varnell since last December, the complaint said.On Friday,&nbsp;Varnell helped the undercover agent build what he thought was a powerful truck bomb using ammonium nitrate and fuel oil, the materials McVeigh used in 1995 to kill 168 people and injure hundreds more.The next day, Varnell&nbsp;parked the truck next to a BancFirst building in downtown Oklahoma City.Varnell also made several cell phone calls that he thought would trigger the blast, the complaint said. The truck and all of the materials, which were inert, were supplied by the FBI.The FBI said&nbsp;Varnell&nbsp;wrote a statement that he wanted posted on social media after the explosion he expected. Varnell said it was &ldquo;retaliation against the freedoms that have been taken away from the American people.&rdquo;The public wasn&rsquo;t at risk during the investigation, said Kathryn Peterson, special agent in charge of the FBI in Oklahoma.&ldquo;I can assure the public, without hesitation, that we had Varnell&rsquo;s actions monitored every step of the way,&rdquo; she said in a statement.
