Although it runs counter to the history of Executive Branch promises of "Two chickens in every pot" and such-like, in reality Congress (which Pelosi and her Dems have controlled for two years) truly controls policy by passing enabling or programmatic laws and then budgeting expenditures for the programs, leaving the President to "Execute" whatever budget authority they choose to grant him, and impotent to carry out any policy he might like but which Congress does not fund.
The main latitude the President has is in response to foreign or domestic emergency situations, for which there are (in effect) slush funds to pay for such contingencies long enough for Congress to decide whether to support the action or pull the rug out from under the President. The Chief Executive can ASK Congress for the laws to bring his desired programs to life, but Congress and Congress alone has the power to formulate enabling legislation and then fund the programs, so it is Congress which has the power to shape those sought by the President (to the point of distortion if they feel like it), or even initiate entirely contrary programs instead.
