(AP) — President Barack Obama is turning down a request from some senators to declassify, before he leaves office, a Senate report documenting the CIA’s harsh treatment of detainees after 9/11.

Sen. Dianne Feinstein of California spearheaded the 6,770-page investigation and has been calling for its public release. A 517-page summary was released in late 2014 but the full report remains classified.

White House counsel Neil Eggleston says Obama has directed that his copy of the report be preserved in his archives. But Eggleston says Obama wants it shielded from public access requests for 12 years. That’s the full period allowed by the Presidential Records Act. He says the administration isn’t pursuing declassification at this time.

After 12 years, a records request to Obama’s archives would prompt a process to consider declassification.
