The non-partisan Congressional Research Service has issued a report explaining specifically the areas in which intelligence was not shared with Congress.  Key graf:

The executive branch generally does not routinely share with Congress four general types of intelligence information:

• the identities of intelligence sources;
• the "methods" employed by the Intelligence Community in collecting and analyzing intelligence;
• "raw" intelligence, which can be unevaluated or "lightly" evaluated intelligence, ⁽¹⁸⁾ which in the case of human intelligence ⁽¹⁹⁾ sometimes is provided by a single source, but which also could consist of intelligence derived from multiple sources when signals ⁽²⁰⁾ and imagery ⁽²¹⁾ collection methods are employed; and,
• certain written intelligence products tailored to the specific needs of the President and other high-level executive branch policymakers. Included in the last category is the President’s Daily Brief (PDB), a written intelligence product which is briefed daily to the President, and which consists of six to eight relatively short articles or briefs covering a broad array of topics. ⁽²²⁾ The PDB emphasizes current intelligence ⁽²³⁾ and is viewed as highly sensitive, in part, because it can contain intelligence source and operational information. Its dissemination is thus limited to the President and a small number of presidentially-designated senior administration policymakers. ⁽²⁴⁾

This should kill the meme that Congress voted for the war having the same intelligence information as Bush.
