The nine-member commission, headed by retired U.S. Judge Laurence Silberman and former Sen. Chuck Robb, D-Va., compiled a 700-page report -- about 600 pages unclassified -- for delivery to the White House, The Washington Post reported.
The newspaper said the report is another tough assessment of failures in U.S. intelligence agencies and proposed changes, including the establishment of a department to judge the threat to the United States from chemical, biological and nuclear weapons.
The U.S. intelligence community, which has borne the brunt of many such reports since Sept. 11, 2001, may be growing tired of being told to change its methods, the newspaper said.
"We've been spending so much time reorganizing, we haven't had time to see if the changes we've already made have worked," an intelligence official, who asked not to be named, told the Post.
