Question: What kind of agency is the employer of David Rossi?

full_context: Document 1: Derek Morgan (Criminal Minds): Derek Morgan is a fictional character on the CBS crime drama Criminal Minds, portrayed by Emmy Award winner Shemar Moore. Morgan specializes in fixations and obsessive behaviors. He is a Supervisory Special Agent of the FBI's Behavioral Analysis Unit, (although has served as interim unit chief for Aaron Hotchner), and has appeared from the series' pilot episode ``Extreme Aggressor '', which was originally broadcast on September 22, 2005. Before he left in season 11, he was one of only three main characters to appear since the first season as`` starring'', while also becoming the only character to appear in all episodes.
Document 2: List of NCIS: Los Angeles characters: Nate and recurring character Rose Shwartz share an unconsummated mutual attraction. This has not been explored further as Peter Cambor is no longer a member of the main cast. Cambor's departure as a main cast member coincides with Nate's reassignment to the Middle East to investigate an Islamic militant group based in Yemen. With the conclusion of that mission in the episode ``Harm's Way '', Nate's current assignment is undisclosed, although it is known that he is remaining in the Middle East for the time being.
Document 3: Federal Bureau of Investigation: The FBI is headquartered at the J. Edgar Hoover Building in Washington, D.C., with 56 field offices in major cities across the United States. The FBI also maintains over 400 resident agencies across the United States, as well as over 50 legal attachés at United States embassies and consulates. Many specialized FBI functions are located at facilities in Quantico, Virginia, as well as a "data campus" in Clarksburg, West Virginia, where 96 million sets of fingerprints "from across the United States are stored, along with others collected by American authorities from prisoners in Saudi Arabia and Yemen, Iraq and Afghanistan." The FBI is in process of moving its Records Management Division, which processes Freedom of Information Act (FOIA) requests, to Winchester, Virginia.
Document 4: Central Intelligence Agency: Unlike the Federal Bureau of Investigation (FBI), which is a domestic security service, CIA has no law enforcement function and is mainly focused on overseas intelligence gathering, with only limited domestic collection. Though it is not the only U.S. government agency specializing in HUMINT, CIA serves as the national manager for coordination and deconfliction of HUMINT activities across the entire intelligence community. Moreover, CIA is the only agency authorized by law to carry out and oversee covert action on behalf of the President, unless the President determines that another agency is better suited for carrying out such action. It can, for example, exert foreign political influence through its tactical divisions, such as the Special Activities Division.
Document 5: Federal Bureau of Investigation: Despite its domestic focus, the FBI also maintains a significant international footprint, operating 60 Legal Attache (LEGAT) offices and 15 sub-offices in U.S. embassies and consulates across the globe. These overseas offices exist primarily for the purpose of coordination with foreign security services and do not usually conduct unilateral operations in the host countries. The FBI can and does at times carry out secret activities overseas, just as the CIA has a limited domestic function; these activities generally require coordination across government agencies.
Document 6: Emily Prentiss: On July 21, 2016 at San Diego Comic - Con International, it was announced that Brewster will be returning in season 12 in a recurring role. On August 30, 2016, it was confirmed that Brewster would once again be a series regular for the 12th season. She was re-hired soon after Thomas Gibson had been dismissed from the show.
Document 7: Federal Bureau of Investigation: The FBI often works in conjunction with other Federal agencies, including the U.S. Coast Guard (USCG) and U.S. Customs and Border Protection (CBP) in seaport and airport security, and the National Transportation Safety Board in investigating airplane crashes and other critical incidents. Immigration and Customs Enforcement Homeland Security Investigations (ICE-HSI) has nearly the same amount of investigative man power as the FBI, and investigates the largest range of crimes. In the wake of the September 11 attacks, then-Attorney General Ashcroft assigned the FBI as the designated lead organization in terrorism investigations after the creation of the U.S. Department of Homeland Security. ICE-HSI and the FBI are both integral members of the Joint Terrorism Task Force.
Document 8: Robert Ressler: Robert Kenneth Ressler (February 21, 1937 -- May 5, 2013) was an FBI agent and author. He played a significant role in the psychological profiling of violent offenders in the 1970s and is often credited with coining the term ``serial killer. ''After retiring from the FBI, he authored a number of books on serial murders, and often gave lectures on criminology.
Document 9: Jennifer Jareau: The season seven premiere reveals that JJ has returned to the Behavioral Analysis Unit, having received the training to become a full - time profiler, instead of the Media Liaison, a position which has been split between Hotch and Garcia.
Document 10: Federal Bureau of Investigation: The Federal Bureau of Investigation (FBI) is the domestic intelligence and security service of the United States, which simultaneously serves as the nation's prime federal law enforcement organization. Operating under the jurisdiction of the U.S. Department of Justice, FBI is concurrently a member of the U.S. Intelligence Community and reports to both the Attorney General and the Director of National Intelligence. A leading U.S. counterterrorism, counterintelligence, and criminal investigative organization, FBI has jurisdiction over violations of more than 200 categories of federal crimes.
Document 11: Federal Bureau of Investigation: The FBI is organized into functional branches and the Office of the Director, which contains most administrative offices. An executive assistant director manages each branch. Each branch is then divided into offices and divisions, each headed by an assistant director. The various divisions are further divided into sub-branches, led by deputy assistant directors. Within these sub-branches there are various sections headed by section chiefs. Section chiefs are ranked analogous to special agents in charge.
Document 12: Federal Bureau of Investigation: Although many of FBI's functions are unique, its activities in support of national security are comparable to those of the British MI5 and the Russian FSB. Unlike the Central Intelligence Agency (CIA), which has no law enforcement authority and is focused on intelligence collection overseas, FBI is primarily a domestic agency, maintaining 56 field offices in major cities throughout the United States, and more than 400 resident agencies in lesser cities and areas across the nation. At an FBI field office, a senior-level FBI officer concurrently serves as the representative of the Director of National Intelligence.
Document 13: Penelope Garcia: Garcia is unabashedly emotional, which sometimes makes her job with the BAU more difficult. She has broken down, crying several times while listening to and watching terrifying things in her office as she analyzes them for the team. However, according to Agent Hotchner, she ``fills her office with figurines and color to remind herself to smile as the horror fills her screens ''. Garcia is, on the whole, an optimist. She has managed to remain so, even though the job occasionally requires her to dig into people's secret lives, to`` find the god - awful thing that happened to them that made them do the god - awful thing to someone else''. Many team members have commented in various ways, that her optimism is an aid to them, that (as Hotch said) they would never want her to change. He once commented to Reid and JJ, after contacting Garcia during a case, ``Remind me to have her drug tested, ''indicating her optimism could even be too much at times. Garcia was once shot by a man with whom she had just gone on a date, but survived when the bullet missed her heart and ricocheted into her abdomen. The attacker (who turned out to be a type of serial killer known as a 'hero homicide') was later killed. After this incident, Morgan insisted she keep a gun; however, it is never shown whether she took this advice. She was romantically involved with fellow FBI Technical Analyst Kevin Lynch (played by Nicholas Brendon).
Document 14: Federal Bureau of Investigation: The FBI director is responsible for the day-to-day operations at the FBI. Along with his deputies, the director makes sure cases and operations are handled correctly. The director also is in charge of making sure the leadership in any one of the FBI field offices is manned with qualified agents. Before the Intelligence Reform and Terrorism Prevention Act was passed in the wake of the September 11 attacks, the FBI director would directly brief the President of the United States on any issues that arise from within the FBI. Since then, the director now reports to the Director of National Intelligence (DNI), who in turn reports to the President.
Document 15: David Rossi: Rossi begins the series returning to the FBI after a lengthy period of being semi-retired, with his return due to "unfinished business". He is shown to be emotionally tied to Aaron Hotchner, as they both worked together during the early days of the Behaviorial Analysis Unit. Rossi is also a writer, and is one of the team's senior and most decorated profilers. He replaced Jason Gideon, who was written out following Mandy Patinkin's abrupt departure from the series.
