This is the first time a newly inaugurated president has had any impact on a current budget." What that means is that normally when a president's inaugurated in January, the budget for the first calendar year of his term or the first nine months is already done. So from January 21st all the way 'til October when the new budget's done, the president has to deal with the previous Congress' budget and has nothing to say about it. What they're saying is that Donald Trump has had a record-breaking, never-before-seen thing by having an impact on the budget in his first year.
