The Wall Street Journal is reporting that the independent commission created to investigate the Sept. 11 attacks is facing major hurdles from the White House and may not be able complete its investigation by its deadline of next May.

Access to White House documents and federal personnel to interview has been limited. The commission has only received a small portion of the documents it requested. And interviews only began last week, seven months after the committee was formed.

And members of the commission were only allowed access to a major 900-page Congressional inquiry two months ago.

Commissioner Max Cleland, a former Democratic senator from Georgia, says of the White House: “It’s obvious that they’re sifting the information to the 9/11 commission now. We’re way, way late here. The picture is not encouraging.”
