Here's a

...
On September 13, 2001, the FBI formed a multi-agency task force--
which is now known as the Terrorist Financing Operations Section
(TFOS)--to combat terrorist financing. The mission of TFOS has evolved
into a broad role to identify, investigate, prosecute, disrupt, and
dismantle all terrorist-related financial and fundraising activities.
The FBI also took action to expand the antiterrorist financing focus of
its Joint Terrorism Task Forces (JTTFs)--teams of local and state law
enforcement officials, FBI agents, and other federal agents and
personnel whose mission is to investigate and prevent acts of
terrorism. In 2002, the FBI created a national JTTF in
Washington, D.C., to collect terrorism information and intelligence and
funnel it to the field JTTFs, various terrorism units within the FBI,
and partner agencies.
Following September 11, representatives of the FBI and Operation
Green Quest met on several occasions to attempt to delineate
antiterrorist financing roles and responsibilities. However, such
efforts were largely unsuccessful. The resulting lack of clearly
defined roles and coordination procedures contributed to duplication of
efforts and disagreements over which agency should lead
investigations. To help resolve these long-standing
jurisdictional issues, in May 2003, the Attorney General and the
Secretary of Homeland Security signed a Memorandum of Agreement on
terrorist financing investigations. According to the Agreement, the
Department of Justice will lead federal law enforcement efforts against
terrorist financing. The Agreement specifies that the FBI
is to lead terrorist financing investigations and operations, utilizing
the intergovernmental and intra-agency national JTTF at FBI
headquarters and the JTTFs in the field. The Agreement also specifies
that, through TFOS, the FBI is to provide overall operational command
to the national JTTF and the field JTTFs.

This
http://www.ccc.nps.navy.mil/si/2005/Jan/clunanJan05.asp">2005 article makes it sound like that the 2003 agreement that gave the FBI control of the the terror financing investigations consisted of an additional Joint Terrorism Task Force:
...
Another bureaucratic battle took place between the U.S. Customs Service and the FBI TFOS over Customs Service’s Operation Green Quest. Both had interagency groups to investigate terrorist financing that overlapped. These were resolved in 2003 with the formation of an FBI-led Joint Terrorism Task Force, but under an agreement to ensure the continued participation of experts at Customs (now the Immigration and Customs Enforcement (ICE) branch of the Department of Homeland Security).<85>

So it's a little murky as to whether or not that 2003 agreement constituted a new JTTF or not. ,Regardless the source of the conflict between the FBI and the other agencies involved is pretty interesting because one of the main cases that caused the dispute between the FBI and the other agencies involved is the investigation resulting from the Operation Greenquest raids of 2002 on the SAAR network/Safa Trust web of Saudi/Muslim Brotherhood charities. Another source of conflict between the FBI and other agencies was the Ptech investigation. Here's a

http://fortherecordessays.blogspot.com/2006/11/part-13-its-jungle-in-here-and-it_11.html">here you can find some more info on the various obstructions of the Operation Greenquest and Ptech investigations and how interrelated the figures in the two cases are. The gist of it is that there was protection before and after 9/11 of groups in this country operated by the Muslim Brotherhood and Saudis (and their affiliates) that were involved with terrorist groups, and the high-level obstruction of investigations into these groups riled a lot of feathers within the various agencies in charge of looking into these things.
Another observation that comes from this particular terror financing JTTF is that it appears that JTTF's can be useful not only for coordinating investigations by agencies with overlapping jurisdictions, but for also killing an investigation by tranfsering control of the JTTF to an agency that, for whatever reason, is less than likely to do a complete investion.
