The plan is to "reduce the size of the federal employees down by 75% by the end of the first term," Ramaswamy told Semafor on Wednesday.
The agencies that would be closed include the FBI; the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF); the Department of Education; the Nuclear Regulatory Commission; and the Department of Agriculture's Food and Nutrition Services, he said.
Ramaswamy pointed out he would use executive action and bypass Congress to close the agencies.
In addition, Ramaswamy said he would also execute "a revision of at least 50% of federal regulations that failed the Supreme Court's test."
The plan does not entail replacing the agencies, however, it does envision relocating some employees to other government units, Ramaswamy said.
For example, 15,000 of the 35,000 FBI employees would be reassigned to roles within the US Marshals Service, the Financial Crimes Enforcement Network and the Drug Enforcement Administration, Ramaswamy added.
