Trump's budget would also slash the EPA's enforcement division, which fines companies for pollution, by 31 percent, doing away with dozens of programs, such as the Energy Star appliance efficiency program aimed at reducing energy consumption.
For example, the proposed cuts to Health and Human Services would eliminate altogether money for the Meals on Wheels program, which provides hot meals to the elderly on fixed incomes. CPB supports 1,500 public radio and TV stations across the country, among them, the National Public Radio.
The Trump budget for the fiscal year that starts in October would reduce NIH funding by $5.8 billion to $25.9 billion, a 22 percent reduction that the administration said would include a major reorganization, reduced administrative costs and a refocusing of resources on "highest priority research".
