Congress as a whole, like the executive branch, adjusted slowly to the rise of transnational terrorism as a threat to national security. In particular, the growing threat and capabilities of Bin Ladin were not understood in Congress.As the most representative branch of the federal government, Congress closely tracks trends in what public opinion and the electorate identify as key issues. In the years before September 11, terrorism seldom registered as important. To the extent that terrorism did break through and engage the attention of the Congress as a whole, it would briefly command attention after a specific incident, and then return to a lower rung on the public policy agenda...

...Third, Congress did not reorganize itself after the end of the Cold War to address new threats. Recommendations by the Joint Committee on the Organization of Congress were implemented, in part, in the House of Representatives after the 1994 elections, but there was no reorganization of national security functions.The Senate undertook no appreciable changes. Traditional issues—foreign policy, defense, intelligence—continued to be handled by committees whose structure remained largely unaltered, while issues such as transnational terrorism fell between the cracks.Terrorism came under the jurisdiction of at least 14 different committees in the House alone, and budget and oversight functions in the House and Senate concerning terrorism were also splintered badly among committees. Little effort was made to consider an integrated policy toward terrorism, which might range from identifying the threat to addressing vulnerabilities in critical infrastructure; and the piecemeal approach in the Congress contributed to the problems of the executive branch in formulating such a policy.

Fourth, the oversight function of Congress has diminished over time. In recent years, traditional review of the administration of programs and the implementation of laws has been replaced by “a focus on personal investigations, possible scandals, and issues designed to generate media attention.” [emphasis mine - Sol] The unglamorous but essential work of oversight has been neglected, and few members past or present believe it is performed well. DCI Tenet told us: “We ran from threat to threat to threat. . . . [T]here was not a system in place to say,‘You got to go back and do this and this and this.’” Not just the DCI but the entire executive branch needed help from Congress in addressing the questions of counterterrorism strategy and policy, looking past day-to-day concerns. Members of Congress, however, also found their time spent on such everyday matters, or in looking back to investigate mistakes, and often missed the big questions—as did the executive branch. Staff tended as well to focus on parochial considerations, seeking to add or cut funding for individual (often small) programs, instead of emphasizing comprehensive oversight projects...

...Each of these trends contributed to what can only be described as Congress’s slowness and inadequacy in treating the issue of terrorism in the years before 9/11. The legislative branch adjusted little and did not restructure itself to address changing threats. Its attention to terrorism was episodic and splintered across several committees. Congress gave little guidance to executive branch agencies, did not reform them in any significant way, and did not systematically perform oversight to identify, address, and attempt to resolve the many problems in national security and domestic agencies that became apparent in the aftermath of 9/11...

In fact, Congress had a distinct tendency to push questions of emerging national security threats off its own plate, leaving them for others to consider. Congress asked outside commissions to do the work that arguably was at the heart of its own oversight responsibilities. Beginning in 1999, the reports of these commissions made scores of recommendations to address terrorism and homeland security but drew little attention from Congress. Most of their impact came after 9/11.
