Q about Jose Escamilla's Movie

In Jose Escamilla's movie: UFO: The Greatest Story Ever Denied, there's a lot of footage of former NASA employee's vowing to testify their knowledge of what NASA's keeps secret about, to congress.

My question is, have these individuals been called to congress to testify? Have they testified? Did NASA retort?

Also, if these individuals independently released the information of what they intended to testify about, does anybody have links where one could read what they talk about?

seems to me you are reffering to disclosure project parts of that movie...

so refference points go to Disclosure project...
just search the web for it,google video at best perhaps...
