Does this mean that a president can take the full amount of an approved budget and allocate to toward a project that was not addressed in the budget. Can he reallocate anything anywhere at will. If it is the legislation to allocate money by project and the president has approval authority, then that is how it should be spent. Now things come up from time to time that require some reallocation. For instance, national disasters. An example would be a terrible hurricane season which required more expenditures than originally anticipated. Not paiting the border wall black. We are only having this conversation because the Senate does not have the backbone to stand up to Trump.
