9/10/19 Power of the purse
 
The power of the purse is the ability of one group to manipulate and control the actions of another group by withholding funding, or putting stipulations on the use of funds. The power of the purse can be used to save their money positively (e.g. awarding extra funding to programs that reach certain benchmarks) or negatively (e.g. removing funding for a department or program, effectively eliminating it). The power of the purse is most often utilized by forces within a government that do not have direct executive power but have control over budgets and taxation.

In the United States

The power of the purse plays a critical role in the relationship of the United States Congress and the President of the United States, and has been the main historic tool by which Congress can limit executive power. One of the most recent examples is the Foreign Assistance Act of 1974, which eliminated all military funding for the government of South Vietnam and effectively ended the Vietnam War.
