Yesterday, Congressmen Walter Jones, Stephen Lynch and Thomas Massie hosted another press conference in their continuing drive to achieve the declassification of a 28-page finding on foreign government support of the 9/11 hijackers. This one, coming two days shy of the 13th anniversary of the September 11 attacks, was marked by emotional appeals from family members of 9/11 victims as well as a survivor at the World Trade Center.

Below, you’ll find the full video of the press conference, including a question-and-answer session that followed prepared remarks. Especially touching are the words of Kaitlyn and Justin Strada, whose father, Tom Strada, was killed at the World Trade Center just four days after Justin was born.

The most sharply-pointed demand for the release of the 28 pages came when Matthew T. Sellitto, whose son Matthew C. Sellitto was killed at the World Trade Center, closed his remarks by saying:

So, if I spoke to (9/11 Commission Chairman) Tom Kean and if I spoke to (9/11 Commission Vice-Chairman) Lee Hamilton, and they told me there’s no security risk, and if the people that gave them the power to run this 9/11 Commission trusted them, and they tell me there’s no security risk, then Mr. President, when you tell me there’s a security risk and that’s the reason you’re not making these public…Mr. President, I call you—a liar. And my son’s dead. And I don’t know all the facts, because Mr. President, you’re lying to me.
