The Kentucky Republican is sponsoring legislation called the “Transparency for the Families of 9/11 Act,” which would force the release of the disputed pages. With his support, an important issue that has languished far too long may be finally gaining traction.

Paul is a big catch for the 28 pages movement, as advocates describe their effort. Former Florida senator Bob Graham, who has been banging the drum on the classified pages for years, will also appear alongside Paul at a press conference at the Capitol on Tuesday morning to lend his gravitas to the occasion.

Graham led the Senate inquiry and drafted the pages that have been kept under wraps. Without violating his oath of secrecy about specifics, the Democrat has been quite outspoken, saying the redacted pages “point a very strong finger at Saudi Arabia as being the principal financier” of the 9/11 attacks. He has also said the U.S. government’s protective stance toward the Saudis allows them to continue spreading the extreme Wahhabi version of Islam that has led to the rise of ISIS.
