Congress will release classified pages detailing alleged Saudi Arabian government ties to the 9/11 hijackers as early as Friday, a law enforcement source told The Post.

The infamous “28 pages” is a redacted section from a 2002 congressional investigation of the 9/11 attacks.

Intelligences agencies, law enforcement and the State Department have reviewed and approved the release of the material with “minimal redactions,” sources told CNN.

Much of what’s in the 28 pages was quietly released by the government last summer as the 17th file in a cache of FBI documents related to 9/11.

First reported by 28pages.org, the file lists some three dozen people who had contact with the hijackers in a section headed “A Brief Overview of Possible Saudi Government Connections to the September 11th Attacks.”

Rep. Adam Schiff, a member of the House Intelligence Committee, said the report would be posted online soon.

“The House Intelligence Committee will get the redacted report today or tomorrow,” Schiff told CNN. “The Senate and House intel committees should then give the formal go-ahead to release the report since they originally produced it.”

Sens. Lindsey Graham (R-SC) and Jeff Sessions (R-Ala.) both told The Post they’d support the release.

Facing pressure from victims’ families and lawmakers, President Obama has said his administration would declassify the much-clamored-for pages.

Former Sen. Bob Graham, who chaired the committee that carried out the probe, recently said he was told the decision about whether to release the pages would be made by June 12.

“Well, we’re now well beyond that date and no decision as to whether a decision is going to made has been released,” he told CNN. “Immediately after June 12th, I began calling the White House to ask what is the new date for the decision to be made and a half-dozen telephone calls have not been returned.”

Last week, House Democrats and Republicans urged the White House to declassify and publicize the pages — and introduced a bill to do so if the president doesn’t act.

“If the Obama administration does not move forward, then we need to pass (the legislation) to have the House Intelligence Committee publish the pages,” said Rep. Stephen Lynch (D-Mass.).

Terry Strada, whose husband was working on the 104th floor of the North Tower when the planes struck on 9/11, has been pushing for the right to sue Saudi Arabia over its alleged involvement in the attack. The couple had had their third child just four days earlier.

“All of this could be settled, if we would just release the 28 pages and let everyone see what’s in there,” said Strada.

“If it was just this low-level … government officials in the Saudi Arabian government, then they have nothing to worry about. The American people deserve this just as much as the 9/11 families deserve it, but we’re the ones that are suffering by not having them released,” she said, CNN reported.

The Saudi government also is calling for the pages to be released so it can address any allegations, which it has long denied.
