They're not "reducing waste".

First, they got rid of all of the people at USAID whose job was to monitor contracts for waste and abuse. Second, they shut down programs with no notice, leaving millions of dollars of food and medicine to spoil. Then, when the inspector general (whose job is to audit and report waste) reported that they were directly causing waste by removing all the internal controls and letting food spoil, they fired the inspector general.

That is not reducing waste. It's using "reducing waste" as a pretext to radically transform the government.
