9/11 families upset after alleged mastermind and two others accept plea deals: "We demand a trial"

On Wednesday, the Defense Department announced that it had reached plea agreements with three terrorists accused of planning the 9/11 attacks, including Khalid Sheikh Mohammed, who is said to have orchestrated the devastation. The families of the victims are furious.

During "Fox & Friends First," President Brett Eagleson, who lost his father in the 9/11 attacks 23 years ago, demanded that government officials investigate Saudi Arabia's role in facilitating the terror.

"Eagleson shared with Todd Piro on Thursday that it was both terrible and shocking. Yesterday, he sat with over 500 family members in the Southern District of Federal Court in Manhattan, where they waited 23 years for a trial in that court. They finally got access to documents that the FBI and the DOJ had shared with them, revealing the role that the Kingdom of Saudi Arabia played."

"Eagleson stated that America's foundation is justice, and therefore, a lawsuit is necessary. A trial and hearing are required to ensure that these individuals are not unjustly imprisoned."

The Department of Defense (DOD) announced on Wednesday that three of the masterminds of the Sept. 11 terror attacks have reached plea agreements with prosecutors, who were awaiting their trial in Guantánamo Bay, Cuba.

Susan Escallier, the Convening Authority for Military Commissions, reached pretrial agreements with Khalid Shaikh Mohammad, Walid Muhammad Salih Mubarak Bin 'Attash, and Mustafa Ahmed Adam al Hawsawi, according to the DOD.

The OMC informed three relatives of 9/11 victims that the terms and conditions of the plea deals were not disclosed, but the terror suspects will not face the death penalty.

It is crucial for the families of 9/11 victims to uncover how Saudi Arabia supported the terrorists, as Eagleson emphasized.

"We want to know what the Kingdom of Saudi Arabia did," Eagleson said. "We want to know what they did. Listen, everything that we've uncovered said that the Kingdom of Saudi Arabia has played a significant role. We now know that 30 individuals helped Saudi Arabian government officials facilitate and support the 9/11 hijackers. These individuals hold the truth to what actually happened on 9/11."

Despite lacking knowledge of English, Western culture, money, and experience in flying planes, 19 individuals managed to execute the most devastating and consequential attack in this country's history without any assistance.

"The government of Saudi Arabia provided them with significant assistance."

The accused defendants are charged with aiding the 19 hijackers who flew commercial planes into the World Trade Center, Pentagon, and a Pennsylvania field on September 11, 2001, by providing training, financial support, and other assistance.

Nearly 3,000 people were killed in the deadliest terror attack on U.S. soil, prompting loved ones of the victims to express outrage upon hearing news of the deal.

They are slated to be sentenced in Guantánamo Bay on Aug. 5

"Eagleson stated that he doesn't really care whether people live or die, as it is up to God to judge. If they choose to rot away in a jail cell or become martyrs, then that may be their fate, but he doesn't take a higher stance on life or death than what is within his pay grade."

He continued, "I need to know what these people know about the Saudi Arabian government's actions that led to my father's death."
