How much in USAID funding did Trump attempt to cancel that had already been approved by Congress?

The correct answer is based on the significant financial actions taken during Trump's presidency regarding USAID funding. The attempt to cancel approximately $5 billion in approved foreign aid highlights the administration's controversial stance on foreign assistance and reallocating federal funds. This figure reflects a substantial portion of the budget that was initially earmarked for various international programs and partners, showcasing the tensions between executive budgetary authority and congressional appropriations. The effort to cancel this funding sparked considerable debate in Congress, as it involved a substantial amount of taxpayer money that had already been vetted and approved for international aid efforts.

The other amounts listed in the options are either inaccurate representations of the budgetary decisions made during that time or do not align with the specific $5 billion figure that was widely reported, emphasizing the magnitude of the attempted cuts.
