“After further review of the redacted version of the executive summary, I have concluded the redactions eliminate or obscure key facts that support the report’s findings and conclusions,” the powerful California Democrat said in a statement Tuesday. “Until these redactions are addressed to the committee’s satisfaction, the report will not be made public.”

Last week, the White House returned the so-called “torture report” to the Intelligence Committee, but Feinstein said she would need to review the redactions before deciding whether to make the report public. Other senators blasted the administration for attempting to conceal embarrassing details contained in the panel’s 500-page executive summary of the larger study.

“Redactions are supposed to remove names or anything that could compromise sources and methods, not to undermine the source material so that it is impossible to understand,” said Sen. Martin Heinrich, a New Mexico Democrat, in a statement. “Try reading a novel with 15 percent of the words blacked out. It can’t be done properly.”
