Byung Pak, the USA attorney for the Northern District of Georgia, announced the arrest of Hasher Taheb of Cumming, Georgia late Wednesday after a monthslong FBI investigation sparked by a tip from the local community "that Taheb had become radicalized".
Hasher Jallal Taheb has been charged with intent to destroy by fire or explosives a building owned by the US.
Forsyth County News wrote that "law enforcement, reportedly including representatives from the FBI, ICE and the U.S. Secret Service" spent Wednesday night searching the home where Taheb is said to live with his mother.
Other locations targeted for destruction were the Washington Monument and Lincoln Memorial.
He also explained which weapons he wanted to purchase: semi-automatic weapons, improvised explosive devices, an anti-tank rocket and hand grenades.
The FBI was contacted in March past year after receiving a tip Mr Taheb had become radicalised, changed his name and planned to travel overseas.
Warriors-Clippers: DeMarcus Cousins debuts with big dunk
The Golden State Warriors are already starting to turn things on, and now they'll be adding DeMarcus Cousins to the fold. Cousins, who missed almost a year of action because of an Achilles injury, fouled out in just 15 minutes of court time.
Law enforcement allege that he had in his possession a "hand-drawn diagram of ground floor of the West Wing" of the White House.
All threats have been neutralized, Pak said in a statement.
The FBI arrested (the alleged terrorist) shortly after he traded his vehicle for weapons and explosives that the FBI gave him.
Investigators said it is believed Taheb was acting alone.
Taheb said they would approach the White House from the back road, causing a distraction for police and then would proceed into the White House, using an antitank weapon to blow open a door and then take down as many people and do as much damage as possible, the affidavit says.
Taheb appeared in a downtown Atlanta court Wednesday in a case brought by the FBI's Joint Terrorism Task Force. Days later, Taheb met with an undercover Federal Bureau of Investigation agent to discuss the auto. Documents show that an Federal Bureau of Investigation informant and an undercover cop partnered with Taheb, and made him believe they would participate in the attack.
