What is being discovered by investigators regarding government spending?

Investigators are uncovering significant evidence of government fraud and financial mismanagement. According to the speaker, they are finding issues that are 'far worse' than initially expected, with billions of dollars in wasteful spending already identified. The investigation is expected to ultimately reveal 'hundreds of billions of dollars worth of fraud' throughout government operations. This suggests a systematic problem of financial abuse that is more extensive than previously acknowledged in public discourse.
