What does POTP mean in Unclassified?

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 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.
