On Wednesday night, agents were searching the home south of Cumming where Taheb is believed to live with his mother.
It wasn’t immediately clear if Taheb had an attorney. Messages seeking comment from family weren’t immediately returned.
The complaint lays out a detailed months-long investigation.
On Aug. 25, 2018, Taheb allegedly put his vehicle up for sale to fund a trip. An FBI informant reached out to show interest and met with the suspect days later.
Taheb allegedly said he planned to travel to “hijra,” a term said to refer to Islamic State territory.
He also told the informant he wanted to attack the White House and Statue of Liberty in jihadist attacks, authorities said. At the beginning of December, Taheb arranged a meeting with the informant and an undercover FBI agent, the complaint said.
“Taheb explained that jihad was an obligation, that he wanted to do as much damage as possible, and that he expected to be a ‘martyr,’” the complaint said.
A few days later, there was another meeting in Alpharetta, during which Taheb allegedly showed the FBI worker a composition notebook with a hand-drawn map of the ground floor of the West Wing in the White House. Taheb seemed to believe the informant and FBI worker would join his plot if they could find weapons, according to the document.
By mid-December, Taheb had allegedly broadened the scope of places he wanted to attack to include the Washington Monument, the Lincoln Memorial and a synagogue. He said he wanted to use handguns, IEDs, an AT-4 anti-armor weapon and hand grenades.
The conversations continued into this month with Taheb allegedly discussing growing the group, disdain for the U.S. and Israel and various angles of the plot. He also expressed worry that his family would catch on to the plans.
The attack on the White House was supposed to involve driving on a road behind the building, creating a diversion and shooting a hole through the building to gain entry and kill people, the complaint said.
On Wednesday, Taheb went to a Buford store parking lot for the purpose of him and the FBI worker exchanging their vehicles for semi-automatic rifles, explosive devices and an AT-4, the complaint said. A second informant inspected the vehicles and told Taheb the money was in the ashtray of one of them.
A second FBI worker drove up with a tractor-trailer, which had the weapons inside, though the FBI had rendered them useless. Taheb took the weapons in a backpack and was arrested by agents.
