The U.S. government on Thursday postponed the release of a full report on CIA's controversial interrogation program for two more months.

Justice Department spokeswoman Tracy Schmaler told reporters that some information in the CIA report overlaps with other CIA documents, so the administration intends to release report and other documents together by Aug. 31.

The government had intended to complete its review of the 2004 report and release it two weeks ago.

But continued interagency debate about how much of the secret report could be made public pushed back the deadline.

The American Civil Liberties Union (ACLU) had sued the government for the public release of all documents related to the CIA's interrogation and detention program.

Last year, the CIA released a report with most of the 109 pages either withheld or heavily blacked out.

The ACLU complained to the court that the CIA was withholding information "not for legitimate security reasons."

After taking office in January, the Obama administration agreed to review the report to see what more could be released.

However, due to political reasons, the report's release has been delayed from time to time.
