prospective aid recipient's unit is searched for evidence of past commission of gross human rights violations. The State Department has interpreted "gross human rights violations" to mean a small number of the most heinous acts: murder of non-combatants, torture, "disappearing" people, and rape as a tactic. The government utilizes the International Vetting and Security Tracking (INVEST) system, which tracks all units and individuals who are potential recipients of assistance, including any information that suggests they are ineligible for assistance and any past determinations regarding their eligibility. Vetting is done at several points in the approval process and by several elements of the State Department, starting at the U.S. embassy in the particular country and occurring at the Bureau of Democracy, Human Rights and Labor (DRL) and the appropriate regional bureau. When a vetter finds credible derogatory information, the information is entered into INVEST, triggering a review with all relevant bureaus. All assistance remains on hold until a final decision is reached. If credible information is found implicating a unit in a gross violation of human rights, the unit will be prohibited from receiving assistance until remediation steps are taken. The law requires the U.S. government to offer assistance to the country's government in bringing those responsible to justice and remediate the sanctioned unit. The process is, in general, not transparent; in June 2016, State Department Spokesperson John Kirby said department officials do not "speak to specific cases on Leahy vetting. We don't do that." While there is no exact definition of what constitutes "credible" information, the State Department's standard is that it need not reach the same standard as would be required to admit evidence in a U.S. court of law. Vetters rely on a wide array of sources including the annual Depart of State Country Reports on Human Rights, US government agency records, NGO human rights reports, and information garnered from the media. Certain countries known as "Fast Track" countries are only required to be vetted at the embassy level. The State Department's Leahy Working Group determines by consensus which countries are eligible for Fast Track vetting. A Fast Track country has a "favorable human rights record, including no serious or systemic problems in the country's security forces and no widespread problems with impunity". The State Department's "Country Reports on Human Rights Practices" is the primary source for Fast Track determination. The Fast Track list is updated annually via
