The US has had inside intel on this connection for a long time, but due the the nature of it's source could not talk about it privately. People would have died.
This info has been shared with memebers of both parties at briefings. Compare and contrast the reactions. Pubbies openly concerned, Dems saying "Nothing new". IMHO, the Dems were banking on much of this never being made public. The connection now is out.
What comes next is "What did the Dems know and when did they know it?".
British tabloids are about as reliable as Pravda was. Note that all the signatures between the parties in this "Baghdad-Al Qaeda connection" are codenamed. Some proof! Very convenient.
One must separate wishful thinking from believeing every piece of British garbage that comes this way.
