"You are aware the budget in operation down south was passed by the previous administrations?"

No actually it isn't.  The previous Congress didn't even pass a budget for the 2017 fiscal year, that ended Sept. 30th.

In the U.S. the President "writes" the budget but it is up to Congress to pass (or not pass) the budget and what Congress passes might have little to no relation to what the President wrote.  With a Republican Congress the budgets "written" by Obama were largely tossed in the trash (much like what happened when George W. Bush was President with a Democrat Congress for fiscal 2008 and 2009).

For the now-finished 2017 fiscal year the previous Congress only passed "continuing resolutions" while the budget was actually passed by the current Congress, partway into the fiscal year.

For the current 2018 fiscal year the budget was written by President Trump and passed, with relatively few changes, by the current Congress.
