The regional JTTFs coordinate their efforts through the interagency National Joint Terrorism Task Force (NJTTF), based at FBI Headquarters in Washington, D.C.][ As of 2003, NJTTF was composed of representatives from 35 federal agencies and fell under the Operational Support Branch of the FBI Counterterrorism Division.
A 2013 report from the Brennan Center for Justice at the NYU School of Law noted that "JTTFs tend to focus on investigative work while fusion centers are geared towards information collection and analysis, but their missions are intimately related and often overlapping"; JTTFs and fusion centers are sometimes "co-located" in the same physical working space.][

Before U.S. Army psychiatrist Nidal Hasan murdered 14 people in a mass shooting at Fort Hood, the JTTF in San Diego had acquired two messages from Hasen to radical Islamic ideologue Anwar al-Aulaqi. Concerned by the content of the messages, the San Diego JTTF contacted FBI Headquarters and the JTTF based in the FBI's Washington Field Office. The Washington Field Office did a limited assessment and concluded that Hasan was not "involved in terrorist activities." In the meantime, agents in San Diego acquired 14 additional emails and messages (12 from Hasan to al-Aulaqi and two from al-Aulaqi to Hasen), but San Diego did not forward these communications to the D.C. JTTF, and neither JTTF took any action.[Lessons from San Diego: Improving Our Ability to Connect the Dots]

Webster investigated the FBI's counterterrorism intelligence in the lead-up to the Fort Hood shooting, and released its final report in 2012. The Webster Commission found that the assessment of Hasan conducted by the FBI and JTTFs was "belated, incomplete, and rushed, primarily because of their workload" and an "exponential growth in the amount of electronically stored information."[ The report did, however, conclude that all the FBI and task force personnel "acted with good intent" and that their mistakes did not result "from intentional misconduct."][

Criticism
After the September 2001 terrorist attacks, the FBI began to establish or intensify working relationships with campus police departments; by January 2003, JTTFs included campus police officers from at least a dozen universities. This prompted some criticism from faculty and student organizations.

In 2010, the Justice Department Office of Inspector General (OIG) issued a report that criticized the FBI for investigating various domestic activist groups from 2001 to 2006, including PETA, the Thomas Merton Center, and the Catholic Worker. The OIG faulted the FBI for providing the OIG "with speculative, after-the-fact rationalizations for their prior decisions to open investigations that IGdid not find persuasive."

'', Oversight and Review Division, Office of the Inspector General, September 2010.
A 2013 report from the Brennan Center for Justice at the NYU School of Law argued that, "The most significant oversight problem with assigning police officers to JTTFs is that there is no mechanism geared towards ensuring compliance with state and local laws. This problem is exacerbated by the fact that rules relating to how police officers should act in the event of a conflict between their federal and state/local obligations are sometimes unknown and almost always unclear."[
