Tawhedi, 27, and his teenage brother-in-law began planning the attack last June. According to the U.S. Department of Justice, the goal was a mass casualty event as voters headed to the polls.
The pair were arrested in October after attempting to purchase two AK-47s and ammo from an undercover fed.
Tawhedi is charged with providing support to a terrorist organization and acquiring firearms to commit terrorism. He pleaded not guilty in November of last year but changed his plea to guilty on Friday, Jun. 13.
Under the plea agreement, Tawhedi faces up to 35 years in prison and fines of up to $500,000. He waived the right to a jury trial and the right to appeal his sentencing.
Tawhedi’s co-conspirator, a Moore high school student who was 17 at the time of the plot, pleaded guilty as an adult in April and faces up to 15 years.
Both men entered the U.S. on special immigrant visas. After completing their sentences, they will be deported to Afghanistan.
