9/11 family members just out of court in their lawsuit against Saudi Arabia are ripping the Biden administration’s decision to strike a plea deal with terror mastermind Khalid Sheikh Mohammed and two accomplices.

“This is shitty timing. It’s just another move to wrap up 9/11 and put it in a box and make it go away,” Brett Eagleson, who was 15 years old when his dad, Bruce, died while working at the Twin Towers on 9/11, told the Herald.

Eagleson spoke just after leaving a Manhattan court where the 9/11 loved ones had their day in court in a showdown with Saudi officials Wednesday, where they declared “it’s about time” for the truth to finally come out.

The lawyers representing thousands of families — including many from Massachusetts — are fighting to keep the case going before a Manhattan judge. Their lawyers argued the 9/11 Commission did not know the level of detail they had uncovered.

“It’s about time to bring home the truth. Bring home disclosure,” said Eagleson right after court.

The judge in the federal case has taken the case under advisement.

But less than a hour later news broke that Mohammed and his fellow al-Qaeda killers would escape the death penalty.
