An Afghan national living in Oklahoma City allegedly plotted to execute a terrorist attack on Election Day to show his support for ISIS, federal prosecutors announced.

Nasir Ahmad Tawhedi, 27, was arrested on Monday in the Western District of Oklahoma as he and his juvenile co-conspirator met with FBI assets to buy two AK-47 rifles, ten magazines, and 500 rounds of ammunition, according to the criminal complaint unsealed on Tuesday. The unnamed co-conspirator was also arrested.

Tawhedi was charged with conspiring and attempting to provide material support and resources to the Islamic State terrorist group and obtaining firearms and ammunition with the intent of committing a violent terrorist attack on U.S. soil. If convicted on both offenses, the defendant could face up to 35 years in prison.

The Afghan immigrant entered the U.S. in September 2021, days after the American military’s botched withdrawal from Afghanistan.

House Committee on Homeland Security chairman Mark Green (R., Tenn.) and House Subcommittee on Counterterrorism, Law Enforcement, and Intelligence chairman August Pfluger (R., Texas) both blamed the Biden-Harris administration’s lenient border policies for allowing terrorists such as Tawhedi to enter the country.

“This Committee has repeatedly warned of the terror threats stemming from the Biden-Harris administration’s failed leadership and disastrous border security policies,” their joint statement reads. “Unfortunately, our calls for transparency regarding the inadequate vetting and screening following the catastrophic withdrawal from Afghanistan continue to go unanswered — and, here, Americans almost paid the price.”

“We appreciate the efforts of law enforcement in thwarting this alleged terror plot on Election Day,” it adds, “but President Biden and Vice President Harris must reverse course on their misguided policies and put the safety and security of the American people first.”

The FBI started looking into Tawhedi in July. That month, he read a text about the rewards that a martyr receives in the Islamic understanding of the afterlife. The FBI then reviewed Google records that showed Tawhedi’s accessing, viewing, and saving ISIS propaganda. The bureau also searched the Telegram app on his iPhone to uncover evidence of the terror plot.

Tawhedi indicated that his attack was planned for Election Day, November 5, according to his seized communications. Following his arrest, the man confirmed that he and his underage co-conspirator planned to target large gatherings of people and die as martyrs during the attack.

Their plan also involved liquidating their family’s assets and resettling their family to Afghanistan. Tawhedi is married to the co-conspirator’s 24-year-old sister.

It was unclear where the attack would have taken place, although a search of Tawhedi’s Google account found a search for “How to access washington dc cameras.” He also searched for whether any states require a license to get a firearm or have passed permitless-gun-carry laws.

The FBI’s field office in Oklahoma City is investigating the case, the Justice Department said.

“We will continue to combat the ongoing threat that ISIS and its supporters pose to America’s national security, and we will identify, investigate, and prosecute the individuals who seek to terrorize the American people,” U.S. Attorney General Merrick Garland said in a statement.

Last month, authorities arrested and charged a Pakistani national who planned to attack attendees of a Jewish center in New York City around the one-year anniversary of Hamas’s October 7 attack on Israel. That man was said to be a supporter of ISIS, which experts say has experienced a resurgence this year.

“This defendant, motivated by ISIS, allegedly conspired to commit a violent attack, on Election Day, here on our homeland,” FBI director Christopher Wray said of Tawhedi. “I am proud of the men and women of the FBI who uncovered and stopped the plot before anyone was harmed. Terrorism is still the FBI’s number one priority, and we will use every resource to protect the American people.”
